Reaction Steps

A solution of 4-(2-bromo-benzoyl)-[1,4]diazepane-1-carboxylic acid tert-butyl ester (500 mg, 1.3 mmol) in 1,4-dioxane.HCl (3 mL) was stirred at 0° C. for 30 minutes. The reaction was monitored by TLC (10% MeOH in CHCl3). The reaction mixture was concentrated under reduced pressure to get a solid, which was washed with ether and dried to afford 400 mg (95.69% Yield) of (2-bromo-phenyl)-[1,4]diazepan-1-yl-methanone hydrochloride.
