Reaction Steps

6-(Methylsulfonyl)-2H-1,4-benzoxazin-3(4H)-one (Intermediate 101) (280 mg, 1.23 mmol) was deprotonated with sodium hydride and alkylated with 2-{4-[(tert-butoxycarbonyl)amino]piperidin-1-yl}ethyl methanesulfonate (Intermediate 6) (1.62 mmol) as described for Intermediate 2. Chromatography on silica gel with dichloromethane/methanol (20:1) gave the product in 66% yield as a yellow gum.
