Versuchsvorschrift

2.78 g (0.008 mol) of diethyl 2,6-dimethyl-4-(4-fluorophenyl)-1,4-dihydro-pyridine-3,5-dicarboxylate dissolved in 25 ml of 1,2-dimethoxyethane, and 0.30 g (0.01 mol) of 80% strength sodium hydride and, after 30 min, 1.43 g (0.01 mol) of methyl iodide are added. The mixture is stirred at room temperature for 3 hours, neutralized with dilute hydrochloric acid and evaporated in vacuo. The residue is purified by chromatography on silica gel (methylene chloride).
