Procedure

6.4 g of 1-allyl-7-chloro-5-(2-fluorophenyl)-1,3-dihydro-2H-1,4-benzodiazepin-2-one in 50 ml of chloroform are treated with 7 g of m-chloroperbenzoic acid and stirred for 16 hours at room temperature. Then the chloroform solution is washed with 1 N sodium bisulfite solution, with 2 N sodium hydroxide and with water. The organic phase is dried over calcium chloride, filtered and concentrated. The residue is recrystallized from ethanol and there is obtained 1-allyl-7-chloro-5-(2-fluorophenyl)-1,3-dihydro-2H-1,4-benzodiazepin-2-one 4-oxide of melting point 183°C.
