Procedure

Iodotrimethylsilane (2.21 mL, 15.46 mmol) is added drop wise to a room temperature solution of benzyl 2-benzamido-7a-(5-bromo-2-fluoro-phenyl)-4,4a,5,7-tetrahydropyrrolo[3,4-d][1,3]thiazine-6-carboxylate (2.93 g, 5.15 mmol) in acetonitrile (44 mL). The reaction is stirred at room temperature for two hours and the solvent is removed in vacuo. The crude product is purified with an SCX column using 3:1 dichloromethane:methanol and then 2:1 dichloromethane:7 N ammonia in methanol to give the title compound (2.098 g, 94%). ES/MS (m/e): (79Br/81Br) 434/436 (M+H).
