Methyl iodide → HCID 12289743, compound

Participants

Reaction Steps

solution of α-{[(3,4-dimethoxyphenethyl)amino]methyl}-5-methyl-2-thiophenemethanol (2.29 g, 0.007 mole, described in Example 16, and the lower alkyl halide, iodomethane (9.94 g, 0.07 mole), in 70 ml benzene is stirred at 25° C for 3 days. The mixture is concentrated under reduced pressure. The residual oil is taken up in methanol and made alkaline with 10% NaOH. The mixture is extracted with chloroform. The extract is washed with water, dried (K2CO3) and concentrated to give a yellow oil, which is purified by chromatography to give the title compound; nmr (CDCl3) δ 2.41 (s, 3H), 2.46 (s, 3H), 2.6 - 2.8 (m, 6H), 3.68 (s, 1H), 3.83 (s, 3H), 3.88 (s, 3H), 4.88 (t, 1H), 6.6 - 6.9 (m, 5H).
