Versuchsvorschrift

1.25 g (4.09 mmol) of 3-[4-(2-cyclopropylphenyl)piperazin-1-yl]-N-methylpropanamine, 150 ml of acetonitrile, 0.645 g (4.09 mmol) of 2-chloropyrimidine-4-carboxamide and 1 g of potassium carbonate are introduced into a 250-ml round bottom flask fitted with a condenser and with a calcium chloride safety tube. The mixture is heated under reflux for 6 h, is allowed to return to room temperature, is partially concentrated and water and dichloromethane are added. The organic phase is separated off, is washed with water and is dried over sodium sulphate, the solvent is evaporated off and the residue is purified by chromatography on a column of silica gel. The oily product obtained crystallises from acetonitrile and is separated off by filtration, is rinsed with diethyl ether and is dried while heated under vacuum. 0.97 g of compound are finally isolated.
