Participants

Reaction Steps

A mixture of 5% palladium on carbon (300 mg) and phenylmethyl [2,3-dihydro-5-methyl-1-[2-(methylphenylamino)-2-oxoethyl]-2-oxo-1H-1,4-benzodiazepin-3-yl]carbamate (500 mg) in MeOH-water 4:1(40 ml) at 40° under nitrogen was treated with ammonium formate (201 mg) and the mixture stirred at 40° for 1 h. The mixture was cooled to 23° and was filtered through hyflo. The filtrate was evaporated in vacuo and the residue partitioned between 2 N sodium carbonate solution and chloroform. The organic phase was dried and the solvent evaporated in vacuo. The residue was purified by chromatography, elution with MeOH-DCM (1:9) gave the title compound(302 mg).
