Procedure

6-Methoxy-2H-1,4-benzoxazin-3(4H)-one (Intermediate 48) (310 mg, 1.73 mmol) was deprotonated with sodium hydride and alkylated with 2-{trans-4-[(tert butoxycarbonyl)amino]cyclohexyl}ethyl methanesulfonate (Intermediate 76) (2 mmol) as described for Intermediate 2. Chromatography on silica gel with dichloromethane/methanol (20:1) afforded the product as a solid (58%).
