Reaction Steps

Racemic N-((4aRS,6RS,7aSR)-7a-(3-bromo-4-fluorophenyl)-6-hydroxy-4,4a,5,6,7,7a-hexahydrocyclopenta[d][1,3]thiazin-2-yl)benzamide (0.492 g, 1.09 mmol) is purified by chiral HPLC: Column: Chiralcel OJ-H 3×25 cm; eluent: 75:25 (methanol:acetonitrile); flow: 40 mL/min at UV 225 nm. The second eluting isomer is isolated to provide the enantiomerically enriched title compound (0.171 g, 35%). ES/MS m/e (79Br/81Br) 449, 451 (M+1).
