Reaction Steps

A mixture of 1,3-dihydro-5-(ethylthio)-1-methyl-2H-1,4-benzodiazepin-2-one (1 eq.) and formic hydrazide (5.8 eq. Aldrich) in n-butanol (0.1 M in benzodiazepine) was stirred at reflux under N2 for 24 hours. An additional 1.67 eq. of formic hydrazide was added and refluxing continued an additional 16 hours. The yellow solution was evaporated in vacuo and the residue was purified via flash chromatography eluting with a gradient from 98:2 to 96:4 CH2Cl2/MeOH.
