An Improved Scalable Preparation of the Antifungal Posaconazole

-

Preparation method of posaconazole

The invention discloses a preparation method of posaconazole. The preparation method comprises the following steps: in a reaction solvent acetonitrile, carrying out a cyclization reaction on SM1 and SM2 under the action of an organic base namely triethanolamine to generate an intermediate 1; in a reaction solvent dimethyl sulfoxide, carrying out a nucleophilic substitution reaction on the intermediate 1 and SM3 under the action of sodium hydroxide to generate an intermediate 2; and in a reaction solvent hydrochloric acid, removing benzyl from the intermediate 2 to obtain a posaconazole crude product: heating and dissolving the posaconazole crude product, crystallizing, filtering, and drying under reduced pressure to obtain posaconazole. The preparation method has the advantages that the reaction conditions are easy to control, the product yield reaches 98.6%, the product separation and purification are simple and convenient, and the method is suitable for industrial production.

Preparation method of high-purity posaconazole

The invention discloses a preparation method of posaconazole, comprising: subjecting BP004b04 and oxalic acid to salt forming to obtain POE; subjecting POE and di-tert-butyl decarbonate to reaction inthe presence of a base to obtain POP, and recrystallizing POP; subjecting POP and POK o reaction in the presence of a base to obtain POR, and removing tert-butyl carbonate protecting group from POR to obtain POS; subjecting the POS to ring closing to obtain POB; subjecting the POB and POA to reaction to obtain posaconazole. Posaconazole prepared via the preparation method has the content of diastereoisomers being /=0.01%, and the overall route has high total yield.
