339 mg {3-[5-(2-Methyl-benzoyl)-thiazol-2-ylamino]-propyl}-carbamic acid tert-butyl ester was added to a solution of 25% aqueous hydrochloric acid in dioxane. The mixture was stirred 1 h at room temperature and maintained overnight in the refrigerator. The mixture was poured into saturated aqueous sodium bicarbonate solution (50 ml). The organics were extracted with dichloromethane (3×50 ml), dried over magnesium sulfate and evaporated under reduced pressure to afford the title compound as yellow foam (254 mg) which was used without further purification.
