Reaction Steps

A solution of ethyl 2-(tert-butoxycarbonylamino)thiazole-5-carboxylate (5 g, 18.36 mmol) and KOH (10.3 g, 184 mmol) in EtOH/H2O (1:1) (60 mL) was stirred at RT for 12 hrs. The solution was acidified with 1N HCl and the precipitate was filtered and dried, yielding 2-(tert-butoxycarbonylamino)thiazole-5-carboxylic acid (3.84 g, 86%) as a white solid.
