実験手順

In 44 ml of methanol were dissolved 2.57 g of dimethyl 4-[2-(4-aminobutoxy)-5-methylsulfonylphenyl]-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (obtained in Reference Example 2) and 0.83 g of glycidyl phenyl ether, and the solution formed was allowed to react at room temperature for 43 hours and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, and the product was eluted with chloroform-methanol (95:5 v/v). Crude crystals were recrystallized from ethanol-ether to give 1.05 g of dimethyl 4-[2-[4-(2-hydroxy-3-phenoxypropylamino)butoxy]-5-methylsulfonylphenyl]-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate.
