Procedure

The procedure of Example 1 was followed except that 3-acetylthiophene (Aldrich) was used in place of acetophenone to prepare the corresponding 2-(thiophene-3-carbonyl)acetonitrile (Steps A and B). 2-Butanone (Aldrich), 2-(thiophene-3-carbonyl)acetonitrile, morpholine, and sulfur were reacted according to the procedure of Step C, Example 1, to afford the desired compound. Yield: 38%; IR (KBr) cm−1: 3337, 3229, 3107, 1576, 1427, 1265, 1162, 855, 736, 719; 1H NMR (CDCl3):δ 1.71 (s, 3H), 2.15 (s, 3H), 6.17 (bs, 2H), 7.30 (d, J=2.2 Hz, 2H), 7.63 (t, 1H, J=2 Hz); yellow solid, mp: 122–123° C. (petroleum ether).
