実験手順
To a mixture of the amine from step (c) above (1.77 g, 10 mmol) and Et3N (2.78 mL, 20 mmol, Aldrich) was added Ac2O dropwise with stirring at room temperature. The mixture was stirred for 30 min at room temperature, diluted with EtOAc (30 mL), washed with water (20 mL) and brine (20 mL), dried over Na2SO4, and filtered. The filtrate was evaporated in vacuo and the residue was purified by silica gel column chromatography, eluting with 80% EtOAc/hexane to give the title compound. MS (ESI, pos. ion) m/z: 219 (M+1).
