Reaction Steps

To a mixture of [(1-phenyl-1,2-dihydro[1,4]oxazino[2,3,4-jk]carbazol-7-yl)oxy]ethanamine (0.58 g, 1.68 mmol) in DMF (10 mL) is added acetic anhydride (0.17 g, 1.68 mmol) and DMAP (0.01 g, 0.082 mmol). The mixture is heated at 85° C. for 45 min, then partitioned between water and ether. The organic layer is washed twice with water, dried over magnesium sulfate and concentrated. Column chromatography (70 g silica gel) using CH2Cl2/acetone (80/20) as eluent gave 0.46 g (71%) of N-{2-[(1-phenyl-1,2-dihydro[1,4]oxazino[2,3,4-jk]carbazol-7-yl)oxy]ethyl}acetamide.
