Reaction Steps
2.8 mmol of thiophene-2-thiocarboxamide was dissolved in 10 ml acetonitrile. 5.6 mmol of N-ethyl-diisopropylamine was added, followed by 3.4 mmol 1-acetyl-3-bromo-piperidin-4-one hydrobromide (prepared according to patent U.S. Pat No. 4,122,083). The reaction mixture was heated to 50° C. for 4 hours, cooled and concentrated. Chromatography of the residue (SiO2; ethyl acetate) yields the title compound as a yellowish gum. MS (m/e): 265.0 (M+H+).
