Reaction Steps

To a flask equipped with a stirrer, condenser, dropping funnel and thermometer are charged 31.3 g. of 2,3-diphenyl-5,6-methylenedioxy indole, 600 ml. of acetic acid and 0.30 g. of ammonium molybdate dissolved in 30 ml. of water. The stirred mixture is heated to 60°-65°C. and then treated dropwise (about 15 minutes) with 30 ml. of 40% hydrogen peroxide. The mixture is maintained at 65° for about 2 hours and then treated with 150 ml. water. The resultant solid is filtered off and recrystallized from chloroform to give 2-benzoylamino-4,5-methylenedioxybenzophenone, m.p. 195°-197°C.
