Reaction Steps

Bromine (3.2 mL, 62 mol) was added to a solution of 2-(2-tert-butoxycarbonylamino-4-pyridyl)-1-(3-methylphenyl)ethanone (20 g, 61 mmol) in acetic acid (60 mL) and the mixture was stirred at 80° C. for 2 hours. After the reaction mixture was cooled to room temperature, the precipitate was filtered to obtain 19 g (yield 81%) of the title compound.
