Reaction Steps

A solution of [2-(4,5-dimethyl-thiazol-2-ylamino)-ethyl]-carbamic acid tert-butyl ester (2.71 g) in methylene chloride (50 ml) was treated with TFA (5 ml) overnight at RT and 1 hour at 60° C. The solvent was evaporated. Ethyl acetate and 1N HCl were added. The separated aqueous layer was extracted under basic conditions with ethyl acetate.
