Participants

Reaction Steps

80% Sodium hydride in oil (102 mg) was added to a solution of phenylmethyl [2,3-dihydro-5-methyl-2-oxo-1H-1,4-benzodiazepin-3-yl]carbamate (1.00 g) in dry DMF (10 ml) under nitrogen. The mixture was stirred for 0.5 h at 23° and was treated with a solution of 2-bromo-N-methyl-N-phenylacetamide (707 mg) in dry DMF (1 ml). The mixture was stirred at 23° for 1 h, partitioned between phosphate buffer solution (pH6.5) and EA, the organic phase was washed with water and dried. The solvent was evaporated in vacuo and the residue was purified by chromatography on alumina. Elution with MeOH-DCM (1:50) gave the title compound (568 mg).
