Reaction Steps

Alternately, 0.75 g of 1,1'-carbonyldiimidazole is added at once to a suspension of 0.79 g of 2-(2-aminobenzyl)imidazole in 38 ml of methylene chloride and the mixture is stirred at room temperature overnight. The resulting precipitate is collected and recrystallized from methylene chloride to give the crude 11H-imidazo[1,2-c][1,3]benzodiazepin-5(6H)-one, m.p. 238°-40°.
