Procedure

Lithium aluminium hydride (1M in diethyl ether, 28.3 ml) was added slowly to a stirred solution of N-[2-(2-thienyl)acetyl]morpholine (3 g) in THF (100 ml). The resultant mixture was heated to 45° C. for 30 minutes. A 2M aqueous hydrochloric acid solution was added dropwise to destroy the excess of reducing agent and the mixture was partitioned between methylene chloride and a 2M aqueous sodium hydroxide solution. The organic phase was washed with brine, dried (MgSO4) and evaporated to give 2-(2-morpholinoethyl)thiophene (1.7 g).
