2-[(4-chlorophenyl)methylamino]benzamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In 400 ml of concentrated aqueous ammonia, 14.4 g of 1-(4-chlorophenylmethyl)-2H-3,1-benzoxazine-2,4(1H)-dione were heated to 100° C. and stirred for 3 hours. After cooling, the crystals were collected by filtration, washed with water and dried. They were recrystallized from ethanol to obtain 8.6 g of title compound. m.p. 138°-139° C. After cooling the crystals were collected by filtration washed with water dried They were recrystallized from ethanol
