Reaction Steps

14.6 g of the product obtained in step (2c) are dissolved in 50 ml of formic acid. The solution is allowed to stand for 6 hours at room temperature and is worked up analogously to Example (1d). A crystalline crude product is thus obtained, which, after recrystallisation from acetonitrile, yields 1,4-dihydro-2,6-dimethyl-4-(m-nitrophenyl)-pyridine-3,5-dicarboxylic acid 3-{2-[p-(2-aminoethoxy)-phenoxy]-ethyl}-ester 5-methyl ester, which has a melting point of 153°-154°.
