Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of (S)-3-Hydroxypyrrolidine Hydrochloride (CAS: 122536-94-1) with high quality, widely used in organic synthesis, synthesis of pharmaceutical intermediates and Active Pharmaceutical Ingredient (API) synthesis. (S)-3-Hydroxypyrrolidine Hydrochloride (CAS: 122536-94-1) is the main intermediate of Darifenacin Hydrobromide (CAS: 133099-07-7)

(S)-3-Hydroxypyrrolidine hydrochloride was synthesized from(S)-4-amino-2-hydroxybutyric acid through silanization and cyclization to yield(S)-3-trimethylsilyoxy-2-pyrrolidinone,which was subsequently subjected to reduction and formation of hydrochloride salt.The influence of different reduction agents,molar ratio,and solvent on the yield was investigated.The optimal conditions were as follows:NaBH4-CH3COOH was used as the reducing agent,1,4-dioxane was used as the solvent,the molar ratio of 2-amino-3-hydroxybutyric acid to NaBH4 and acetic acid was 1:5:5,and the reaction time was 5 h at 110～120 ℃.The overall yield of target compound was increased to 65%.The process has such advantages as inexpensive reagents,high yield and simple operation.

Darifenacin Hydrobromide (CAS: 133099-07-7), an orally active, once a day selective M3 receptor antagonist, was launched for the treatment of overactive bladder in patients with symptoms of urge urinary incontinence, urgency and frequency. The drug selectively inhibits M3 receptor in the detrusor muscle while sparing the M1 and M2 receptors that are believed to be involved in central nervous system and cardiovascular function respectively. The compound was originally developed by Pfizer and licensed to Novartis and Bayer.
