Procedure

11.15 g (0.065 Mol) of 4-(2-Chloro-ethoxy)-phenylamine is suspended in 150 mL (1.18 Mol) of dimethylamine (40% in water; Fluka 38940) and heated under stirring in a steel pressure reactor at 4 bar for 21 h. After cooling the reaction mixture is diluted with 150 mL of 2N NaOH and extracted with ethyl acetate. The combined organic layers are washed with water, dried (Na2SO4), filtered and evaporated under reduced pressure to obtain 4-(2-dimethylamino-ethoxy)-phenylamine. Title compound: ES-MS: 181 [M+H]+; single peak at tR=1.10 min (System 1).
