Procedure

After 5.5 g (0.0157 moles) of 1-(p-chlorophenoxy)-3-(N-carbomethoxymethyl-N-phenylamino)-2-propanol and 6.0 g (0.059 moles) of acetic anhydride were dissolved in 30 ml of pyridine and left to stand at the room temperature for 20 hr, the reaction mixture was concentrated. The resulting residue was poured into iced water to afford precipitates. The precipitates were collected by filtration, washed with water and dried. Recrystallization from isopropanol gave 5.1 g (83%) of the crystals, m.p. 82°-83°.
