Reaktionsschritte

Following a procedure similar to that described in Example 6, but using 0.42 g of dimethyl 4-(2-oxopropoxy)phenylmalonate (prepared as described in Preparation 38), 0.26 g of 2-amino-1-(3-chlorophenyl)ethanol (prepared as described in Preparation 8), 50 ml of dry benzene, 50 ml of absolute methanol and 0.9 g of sodium cyanoborohydride, and then purifying the reaction product by column chromatography through silica gel, using ethyl acetate as the eluent, 0.4 g of the title compound was obtained, having an Rf=0.28 (thin layer chromatography over silica gel, using ethyl acetate as the developing solvent).
