Reaction Steps

2-Isopropoxy-6-pentadecyl benzaldehyde (3.1 g, 8.3 mmol) and methyl acetoacetate (0.96 g, 8.3 mmol) were dissolved in n-butanol (20 mL). Acetic acid (0.5 g, 8.3 mmol) and piperidine (0.7 g, 8.3 mmol) were added and stirred at room temperature for 3-4 hrs. methyl-3-amino crotonate (0.97 g, 8.3 mmol) was then added and refluxed for 10 hrs. n-Butanol was evaporated and reaction mixture was washed with distilled water and extracted with dichloromethane (10 mL). Organic layer was dried over sodium sulfate, evaporated and compound was purified by column chromatography using silicagel (100-200 mesh) with hexane:EtOAc (94:6) solvent system to give dimethyl 1,4-dihydro-4-(2′-isopropoxy-6′-pentadecylphenyl)-2,6-dimethyl-3,5-pyridine dicarboxylate as viscous liquid.
