A solution of 52.5 ml l-dimethylamino-2-chloroethane in 200 ml toluene is added at a temperature below 20°C the mixture is refluxed for 20 h and cooled, and 100 ml t-butanol are added. The mixture is agitated for 1 h at room temperature, 35 ml ethanol are added, and the mixture is again agitated for 30 min at room temperature. It is then extracted with 2 N hydrochloric acid the acidic phases are washed with ether, made alkaline by the addition of sodium hydroxide solution, and extracted with ether the ethereal phases are washed with water, dried over magnesium sulphate and then distilled to dryness under a vacuum. The residue is dissolved in 100 ml methanol 300 ml of a saturated solution of fumaric acid in methanol are added the methanol is distilled off and replaced by ethyl acetate. Crystallization is allowed to commence and the mixture is cooled with ice for 30 min and suction-filtered the precipitate is washed with water and dried.
