Procedure

A mixture of morpholine (3.2 g, 37 mmol) and 1-(4-fluorophenyl) ethanone (1.5 g, 11 mmol) is heated at 120° C. The conversion of the 1-(4-fluorophenyl) ethanone is complete after 10 hours. Water (10 ml) is than added into the reaction mixture. The precipitate is filtered off, washed with water and dried under vacuum (30° C.) to give 2.1 g of the title-compound. Yield: 93%; m.p. 95-96° C.; MS 205 (100, M+); H1 NMR (CDCl3): δ 7.99 (d, 2H), 6.86 (d, 2H), 3.86 (t, 4H), 3.30 (t, 4H), 2.53 (s, 3H); C13 NMR (CDCl3): δ 196.76, 154.43, 130.55, 128.36, 113.48, 101.16, 66.7, 47.73, 26.37.
