실험 절차
Iodotrimethylsilane (10 mL, 70 mmol) is added to a solution of benzyl (4aR,7aS)-2-benzamido-7a-phenyl-4,4a,5,7-tetrahydropyrrolo[3,4-d][1,3]thiazine-6-carboxylate (11 g, 23 mmol) in acetonitrile (165 mL), stirred at room temperature for 2 hours and concentrated. The mixture is diluted with water (100 mL) and ethyl acetate (150 mL) and the pH adjusted to 4 with 1 M hydrochloric acid. The aqueous layer is collected. The pH of this aqueous layer is then adjusted to 10 with 2 M sodium hydroxide. The resulting solution is then extracted with ethyl acetate (100 mL), dried over magnesium sulfate and concentrated to give the title compound (31 g, 63%). ES/MS (m/e): 338 (M+H).
