Procedure
To a suspension of 5-[2-(tert-butoxycarbonylamino)ethylthio]-3-nitroimidazo[1,2-a]pyridine (364 mg, 1.08 mmoles) in methanol (3 ml) was added conc. hydrochloric acid (2 ml) and the mixture was stirred at room temperature for 1 hour. Then, the solvent was distilled off to obtain 340 mg of the desired product (quantitative, brown solid).
