Description
Technical field
The invention belongs to field of medicine and chemical technology, in particular to a kind of new preparation method of Tedizolid Phosphate.
Background technique
Tedizolid Phosphate (tedizolid phosphate), (R) -3- (4- (2- (2- methyl tetrazolium -5- base) pyridine -
5- yl) 3- fluorophenyl) -5- hydroxyl first base oxazolidine -2- ketone dihydrogen phosphoric acid ester (formula I), the medicine is for treating gram-positive bacteria sense
Dye, such as infection and pulmonary infection etc. caused by acute bacterial skin infection, MRSA.
Currently, there are mainly two types of for the preparation method of disclosed Tedizolid Phosphate：
Route 1：CN1894242 is disclosed following preparation method：
Route first step reaction uses toxic organotin reagent, and second step condensation reaction prepares key intermediate (R)-
The yield of 3- (4- (2- (2- methyl tetrazolium -5- base) pyridine -5- base) 3- fluorophenyl) -5- Qiang Jia Ji oxazolidine -2- ketone down to
26%, third step reaction prepares (R)-[3- (4- (2- (2- methyl tetrazolium -5- base) pyridine -5- base) -3- fluorophenyl) -2- oxygen -5-
Oxazolidinyl] methyl acid phosphate bis- (tetrabutyl esters) needs to carry out at -78 DEG C, and the reaction time is long, and final step is needed using with thorn
Swash the trifluoroacetic acid of stink, strong corrosive.Therefore, the route total recovery is low, high production cost, severe reaction conditions, generates week
Phase is long, and agents useful for same is toxic or irritation corrosivity is strong, is not suitable for industrialized production.
Route 2：CN102177156 discloses following synthetic route：
The route is long by starting material synthetic reaction route, and wherein the reaction of second step boronation need to be carried out in -72 DEG C of low temperature
And the yield of obtained product 4- (benzyloxycarbonyl amino) -2- fluorobenzoic boric acid is only 66% and very impure, the 4th step cyclization is anti-
Answer the complex for operation step and reaction time long, final step phosphorylation is using hypertoxic fuming liquids phosphorus oxychloride.Therefore, the road
Line is also not suitable with industrialization large-scale production.
There are many defects for the synthetic method of Tedizolid Phosphate disclosed in the prior art, therefore still need to prepare phosphoric acid specially
The new method of azoles amine.
