Reaction Steps
2-[2-Aminoethoxymethyl]-3-ethoxycarbonyl-4-(2-chlorophenyl)-5-methoxycarbonyl-6-methyl-1,4-dihydropyridine (0.5 g), triethylamine (0.3 ml) and 2-chloroethylisothiocyanate (0.16 ml) were dissolved in methylene chloride (5 ml) and the mixture was stirred at room temperature for 2 hours. The mixture was then washed with water (5 ml), dried, filtered and evaporated to give a gum. Chromatography of the gum on silica "Kieselgel 60H" (Trade Mark) eluting initially with toluene then with chloroform with a trace of methanol gave the title compound, which was recrystallised from ether, yield 0.102 g, m.p. 145°-147°.
