Abstract
The invention discloses a preparation method of 2-morpholinyl-substituted pyrimidine compounds, comprising the following steps of: carrying out reaction on morpholine and S-methyl-iso-thiourea sulfate, which are taken as raw materials, to obtain moroxydine sulfate, and carrying out reaction on moroxydine sulfate which is taken as a synthon and different 1, 3-dicarbonyl compounds respectively to obtain a series of 2-morpholinyl-subsitiuated pyrimidine compounds. The preparation method is simple in operation technology, and the problem of poor selectivity due to the fact that the pyrimidine ring is firstly synthesized, and is substituted by morpholine can be avoided.
Description
Technical field
The present invention relates to a kind of preparation method, specifically relate to the preparation of 2-morpholinyl substituted pyrimidines compounds.
Background technology
Pyrimidines is the important heterogeneous ring compound of a class in the organic chemistry, is used widely in fields such as chemical pharmacy, fine chemistry industries in recent years.The pyrimidines that the 2-morpholinyl replaces has certain activity, is the important intermediate of pharmacy field.
Traditional synthetic method generally is earlier synthetic pyrimidine ring, and then replaces with morpholine.When other being arranged can be with the functional group of morpholine radical reaction the time on pyrimidine ring, selectivity is relatively poor, and yield is lower, therefore reaction substrate is had certain requirement.
Summary of the invention
The objective of the invention is when solving synthetic 2-morpholinyl substituted pyrimidines compounds and since exist on the substrate different can be with the functional group of morpholinyl reaction the time selectivity relatively poor, be difficult to be fixed the compound of structure.And entire operation technology is simple, and the Moroxydine vitriol that makes is as an important synthon, can with the corresponding pyrimidines of a series of dicarbonyl compound prepared in reaction.
Realize that above-mentioned purpose technical scheme of the present invention is, a kind of synthetic method of brand-new preparation 2-morpholinyl substituted pyrimidines compounds, described reaction is raw material with morpholine and S-methyl-isourea, at first reaction makes Moroxydine vitriol, and then prepare pyrimidines with the cyclization of 1,3-dicarbonyl compound.
This reaction may further comprise the steps:
(1) be raw material with morpholine and S-methyl-isourea, reaction obtains Moroxydine vitriol in the aqueous solution;
(2) Moroxydine vitriol is with different 1, and the reaction of 3-dicarbonyl compound obtains the pyrimidines that a series of 2-morpholinyls replace.
Wherein, whether fully reaction is to determine by liquid chromatography.
The present invention compared with prior art has following beneficial effect: (1) the present invention is raw material with morpholine and S-methyl-isourea, can obtain an important synthon Moroxydine vitriol; (2) Moroxydine and a series of 1, the reaction of 3-dicarbonyl compound obtains corresponding pyrimidines, has avoided the yield that causes owing to reason optionally low, can synthesize the pyrimidine compound of ad hoc structure.
Embodiment
For ease of the understanding of technical solution of the present invention, be introduced below in conjunction with concrete embodiment.
Embodiment 1:
In the 1L there-necked flask, add 80gS-methyl-isourea, 50g morpholine, 300mL water, backflow stirring reaction 4h.Distill out 150mL water, residuum is cooled to 10 degree, with gained white solid suction filtration, dries, and gets Moroxydine vitriol 72g, yield 74%.
Embodiment 2:
Add 200mL ethanol in the 1L there-necked flask, add 11g sodium then in batches, disposable adding 60g Moroxydine vitriol after reaction finishes drips the 45g diethyl malonate, then back flow reaction 5h.The after-filtration that finishes is removed inorganic salt, filtrate be spin-dried for yellow solid, ethyl alcohol recrystallization obtains white solid product 2-morpholinyl-4,6-dihydroxy-pyrimidine 46g, yield 88%.
Embodiment 3:
In the 1L there-necked flask, add 200mL ethanol, 60g Moroxydine vitriol, refluxing drips 43g tetramethoxy propane, back flow reaction 4h then down.Revolve after finishing to steam and remove ethanol, gained is regulated pH=10 with body and function 10% sodium hydroxide solution, separates out white solid.Suction filtration, the oven dry, get 2-morpholinyl pyrimidine and remove by filter inorganic salt, filtrate be spin-dried for yellow solid, ethyl alcohol recrystallization obtains white solid product 2-morpholinyl-4,6-dihydroxy-pyrimidine 32g, yield 74%.
Technique scheme has only embodied the optimal technical scheme of technical solution of the present invention, those skilled in the art to some part wherein some changes that may make all embodied principle of the present invention, belong within protection scope of the present invention.
Claims (1)
1. method for preparing 2-morpholinyl substituted pyrimidines compounds, it is characterized in that in the 1L there-necked flask, adding 200mL ethanol, 60g Moroxydine vitriol, refluxing drips 43g tetramethoxy propane, back flow reaction 4h then down, revolve after finishing to steam and remove ethanol, the gained solid is regulated pH=10 with 10% sodium hydroxide solution, separates out white solid, suction filtration, oven dry gets 2-morpholinyl pyrimidine.
