Description
Technical field
The present invention relates to pharmacy field, be specifically related to Eliquis containing two crystal water
The preparation method of H2-2 crystal formation.
Background technology
Eliquis (Apixaban), chemical name: 1-(4-p-methoxy-phenyl)-7-oxo-6-[4-(2-oxo-piperidino) phenyl]-4,5,6,7-tetrahydrochysene-1H-pyrazolo [3,4-c] pyridine-3-carboxamide, U.S. chemical abstract registration number CAS:503612-47-3, has the structural formula shown in following formula A; Eliquis is the direct inhibitor of the oral Ⅹ a factor of the 3rd approval listing, is developed jointly, for hip joint or the replacement knee in arthroplasty adult patients of selecting a time, to prevent venous thrombosis by Pfizer and Bristol Myers Squibb; Little and the multiple cancellation of possibility that is good due to its drug safety, drug interaction, is expected to the special population for suffering from hepatopathy or renal function damage.
In the document of current report, WO2003049681, US20060069258, WO2010030983, CN101967145, CN104045637 etc. disclose the preparation method of Eliquis and the preparation method of H2-2 crystal formation in succession, but the crystal form purity prepared is lower, the demand of people cannot be met.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, now provide one to prepare high
The preparation method of the H2-2 crystal formation containing two crystal water of the Eliquis of purity crystal formation.
For achieving the above object, technical scheme of the present invention is: the preparation method of the H2-2 crystal formation containing two crystal water of Eliquis, and its innovative point is: comprise the following steps:
(1) 100g Eliquis is placed in the DMF of 1L, is heated to 55 ~ 60 DEG C, fully stir until Eliquis dissolves completely;
(2) hot solution obtained in step (1) is instilled in 2L purified water, keep temperature to be no more than 30 DEG C;
(3) carry out naturally cooling after dripping off, then stir 1h, after stirring, then select Büchner funnel to filter;
(4) in clear water, clean twice by through filtering the filter cake obtained, gained solid adopts vacuum drying oven to carry out drying under reduced pressure and obtains H2-2 crystal 94-99g.
Further, the temperature in described step (2) is 20 ~ 30 DEG C.
Further, 15 ~ 25 DEG C are cooled in described step (3).
Beneficial effect of the present invention is as follows: the present invention is through dissolving, cooling, stir, filter and drying step, and complete the preparation of Eliquis H2-2 crystal formation, the crystal purity of gained is high, simple to operate, is conducive to factorial praluction.
