Participants

Reaction Steps

A mixture of (3RS)-1-[2-(2-chloroethoxy)ethyl]-1,3-dihydro-3-(2-indolylcarbonylamino)-5-phenyl-2H-1,4-benzodiazepine-2-one (700 mg), potassium phthalimide (610 mg) and N,N-dimethylformamide (5 ml) was stirred for 7 hours at 80°-90° C. The reaction mixture was poured into a cold water (100 ml) and extracted with ethyl acetate. The extract was washed with water, dried over magnesium sulfate and evaporated to give (3RS)-1-[2-(2-phthalimidoethoxy)ethyl]-1,3-dihydro-3-(2-indolylcarbonylamino)-5-phenyl-2H-1,4-benzodiazepine-2-one (0.9 g).
