Versuchsvorschrift
To a pressure vessel containing acetonitrile (40 mL) and potassium carbonate (4.0 g, 29.2 mmol) was added 5-[3-(methyloxy)-4-nitrophenyl]-1,2,3,6-tetrahydropyridine (1.7 g, 7.3 mmol) and 2-iodopropane (1.85 g, 10.9 mmol). The reaction was stirred at 85° C. overnight. After removal of the solvent under reduced pressure the residue was diluted with ethyl acetate (30 mL) and washed with water (40 mL). After partitioning and extraction of the aqueous layer (Ethyl acetate 2×15 mL), the organic layer was dried over sodium sulfate, filtered, concentrated and purified via chromatography on SiO2 to afford 1-(1-methylethyl)-5-[3-(methyloxy)-4-nitrophenyl]-1,2,3,6-tetrahydropyridine (1.6 g, 80% yield.) ESIMS (M+H)+=277.1.
