Reaction Steps

To a mixture of 2-[(5-methyl-1-phenyl-1,2-dihydro[1,4]oxazino[2,3,4-jk]carbazol-7-yl)oxy]-1-ethanamine (0.0.442 g, 1.23 mmol) in DMF (10 mL) is added acetic anhydride (0.126 g, 1.23 mmol) and DMAP (0.08 g, 0.66 mmol). The mixture is heated at 95° C. for 1 h and then partitioned between water and ether after cooling. The organic layer is washed three times with water (60 mL), dried over magnesium sulfate and concentrated to give 0.49 g (99%) of N -{2-[(5-methyl-1-phenyl-1,2-dihydro[1,4]oxazino[2,3,4-jk]carbazol-7-yl)oxy]ethyl}acetamide.
