To a solution of 2.60 g (14.6 mmol) of 4-morpholinoaniline in 20 ml of methylene chloride were added 14.07 ml (105 mmol) of triethylamine and 3.53 g (17.5 mmol) of 4-nitrophenyl chloroformate under ice-cooling, followed by stirring at room temperature for 7 hours. After the solvent was evaporated, water was added to the residue, and the precipitated crystals were collected by filtration, washed water, and dried to give 4-morpholino-N-(4-nitrophenoxycarbonyl)aniline.
