Procedure

A mixture of 5 g (23 mmol) of 2-(2'-methylphenoxymethyl)-aniline (Example 1b), 5 g (36 mmol) of K2CO3 and 3.4 g (24 mmol) of methyl iodide in 50 ml of dimethylformamide is stirred overnight at room temperature. The reaction mixture is diluted with water and the aqueous phase is extracted three times with methyl tert-butyl ether. The combined organic phases are extracted with water, dried over MgSO4 and evaporated down. The residue is purified chromatographically using mixtures of hexane and methylene chloride. There is obtained 3.0 g (70% purity, about 40% yield) of the title compound as a yellow oil.
