Procedure

1 mmol of 1-(2-Thiophen-2-yl-6,7-dihydro-4H-thiazolo[5,4-c]pyridin-5-yl)-ethanone was refluxed for 30 min. in 15 ml of 2 M aqueous hydrochloric acid. The reaction mixture was cooled and made alkaline by addition of sodium carbonate. Extraction with ethyl acetate yields the title compound as a brownish solid. MS (m/e): 223.3 (M+H+).
