반응 단계
7-methoxyquinoxalin-2(1H)-one (Intermediate 148, 300 mg, 1.70 mmol) was deprotonated with sodium hydride (100 mg, 60% in oil, 2.56 mmol) and alkylated with 2-{4-[(tert-butoxycarbonyl)amino]piperidin-1-yl}ethyl methanesulfonate (Intermediate 6) (3.4 mmol) as described for Intermediate 2. Chromatography on silica gel with 25% acetone in hexanes gave 200 mg (29%) of the product as a colorless solid.
