Reaction Steps
2H-1,4-Benzoxazin-3(4H)-one (298 mg, 2.0 mmol) was deprotonated with sodium hydride and alkylated with 2-{4-[(tert-butoxycarbonyl)amino]piperidin-1-yl}ethyl methanesulfonate (Intermediate 6) (2.0 mmol) as described for Intermediate 2. Chromatography on silica gel with dichloromethane/methanol (20:1) gave the product in 63% yield as a yellow gum.
