반응 단계
A suspension of 2-bromoacetamidobenzophenone (275 g, 0.86 mol) in methanol (1 L) was treated with a solution of saturated ammonia in methanol (3 L), and the resulting solution was stirred at ambient temperature for 6 h, then was heated at reflux for an additional 4 h. After cooling, water (500 mL) was added, and the solution was concentrated by evaporation to about 1 L in volume, yielding crystalline 2,3-dihydro-5-phenyl-1H-1,4-benzodiazepin-2-one (20) (200.7 g, 98%).
