実験手順

A solution of 2-{[4-(2-chlorophenyl)-3-ethoxycarbonyl-5-methoxycarbonyl-6-methyl-1,4-dihydropyridin-2-yl]methoxy}-acetylhydrazine (0.87 g), 2-methylisothiourea sulphate (0.68 g) and 1,5-diazabicyclo[4.3.0]non-5-ene (0.74 g) in n-butanol (30 ml) was heated under reflux for 16 hours and then evaporated. The residue was partitioned between dichloromethane and water and the organic layer dried (Na2SO4) and evaporated. The residual oil was purified by chromatography on silica (t.l.c. grade, 10 g) using dichloromethane plus 0-100% v/v ethyl acetate as eluant. Appropriate fractions were combined and evaporated and the residual oil triturated with ethyl acetate. The resulting solid was collected, washed with ethyl acetate and dried to give the title compound (0.14 g), m.p. 199°-202° C. decomp.
