Procedure

2-(2-Thienyl)acetyl chloride (16 g) was added slowly to a stirred mixture of morpholine (17.5 ml) and methylene chloride (150 ml). A further portion (5 ml) of morpholine was added and the mixture was stirred at ambient temperature for 4 hours. The reaction mixture was washed in turn with 2M aqueous hydrochloric acid, a saturated aqueous sodium bicarbonate solution and brine. The organic phase was dried and evaporated. The residue was triturated under a mixture of hexane and diethyl ether to give N-[2-(2-thienyl)acetyl]morpholine (20.9 g).
