Versuchsvorschrift

20.1 g (50 mmols) of 2-hydroxyethyl isopropyl 2,6-dimethyl-4-(3-nitrophenyl)pyridine-3,5-dicarboxylate (Example 1) were dissolved in 75 ml of pyridine. 5.9 g (75 mmoles) of acetyl chloride were added to this. After the exothermic reaction was over, the reaction mixture was stirred at room temperature for 3 hours, poured into water and extracted with CH2Cl2. The organic extracts were washed with dilute hydrochloric acid and, after drying over sodium sulphate, evaporated in vacuo. The resulting oil crystallized completely, it was stirred with petroleum ether, filtered off with suction and dried.
