Reaction Steps

A disposable tube was charged with 9-fluoro-4,5-dihydro-1H-benzo[b][1,4]diazepine-2(3H)-thione (40 mg, 0.204 mmol) and a stirbar. nBuOH (5 mL) was added, followed by acetohydrazide (30.2 mg, 0.408 mmol), and the solution was stirred at 130° C. overnight. The solution was concentrated with celite and purified by silica gel chromatography (eluting with methylene chloride/methanol/1% ammonium hydroxide) to yield 10-fluoro-1-methyl-5,6-dihydro-4H-benzo[b][1,2,4]triazolo[4,3-d][1,4]diazepine as an off-white amorphous solid (0.022 g, 0.101 mmol, 50%).
