Procedure

A solution of the halohydrin, α-(bromomethyl)-2-thiophenemethanol (11.4 g, 0.055 mole), described in Example 4, and the primary amine, 3,4-dimethoxyphenethylamine (15 g, 0.083 mole), in 200 ml toluene is heated at reflux for 12 hr. The mixture is cooled to 25° C, shaken with 10% NaOH and the layers separated. The aqueous layer is extracted with chloroform and the combined organic phases washed with water and brine, dried (K2CO3) and concentrated. The resulting dark brown oil is purified by chromatography on silica gel to give the title compound as an oil; nmr (CDCl3) 2.9 (m, 6H), 3.45 (2H), 3.85 (s, 6H), 5.05 (m, 1H), 6.7 - 7.3 (m, 6H).
