Procedure

Sodium azide (53 mg) and copper (II)acetate (19.9 mg) were added to a solution of (±)-N,N-bis(t-butoxycarbonyl){(4aR*,7aS*)-7a-[3-chloro-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)phenyl]-4,4a,5,6,7,7a-hexahydrocyclopenta[d][1,3]thiazin-2-yl}amine (1.16 g) in methanol (20 mL). The mixture was stirred at room temperature for six days. Brine was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound (58.0 mg).
