Procedure

2.23 g 5-Thiophen-2-ylmethyl-oxazole-4-carboxylic acid methyl ester were suspended in 80 ml 6 N hydrochloric acid and stirred for 5 hours at 95° C. The solvent was removed at 30° C. under vacuum and the residue was suspended in ethylacetate, filtered and dried to yield 1.52 g (79%) 1-amino-3-thiophen-2-yl-propan-2-one hydrochloride; MS (ISP): m/e=156 (M+H+).
