Procedure

A solution of benzyl [(3R)-3-(3,5-difluorophenyl)-1-oxido-5-oxothiomorpholin-4-yl]acetate (24.5 mg, 0.062 mmol, minor isomer, from the preparation of Intermediate 4, Step B) in MeOH (2 mL) was purged with nitrogen. The septum sealing the reaction vessel was briefly removed to allow introduction of Pd/C (˜6 mg, 10% Pd/C). The vessel was then purged with hydrogen from a balloon, before a fresh balloon of hydrogen was attached. After LCMS analysis indicated that the reaction was progressing slowly, a suspension of 10% Pd/C was introduced via syringe. After 2.25 hours the hydrogen atmosphere was replaced with nitrogen. The mixture was then filtered through a pad of celite, washing with MeOH as needed. The filtrate was concentrated in vacuo to provide the title compound, which was used without further purification. MS: m/z=304 (M+1).
