Reaction Steps
125 g of N-BOC-p-aminomethylacetophenone ethylene ketal are heated for 15 minutes at 65° in 250 ml of methanol and 250 ml of acetic acid as well as 50 ml of water. The reaction mixture is cooled to 0°, adjusted to a pH of 10 with 10N aqueous NaOH, extracted with ethyl acetate and washed neutral with saturated aqueous NaCl solution. The crude product obtained after drying and concentrating by evaporation is crystallised from hexane. N-BOC-p-aminomethylacetophenone having a melting point of 73°-75° is obtained. IR: 3420, 1707, 1680, 1607, 1500 cm-1 (CH2Cl2). UV: 250 nm (15700) in C2H5OH.
