The product amide is made by the method employed for the preparation of Invention Compound V, which uses carbonyl diimidazole in order to activate piperonylic acid, or piperonyloyl chloride (available from Aldrich) can be combined with 1,2,3,6-tetrahydropyridine either in a suitable anhydrous solvent or without solvent. In either case, the isolation of product is performed in the same manner as done for Invention Compound V to give Invention Compound III as a white solid. EIMS m/z=231 (parent, 149 (base), and 121. 1H NMR δ 2.21 (br s, 2), 3.4-4.3 (br m, 4), 5.87 (m, 2), 6.00 (s, 2), 6.83 (d, 1, J=7.84 Hz), and 6.92-6.96 (dd and d, 2). 13C NMR δ 101.3 (--OCH2O--) and 169.9 ppm (carbonyl).
