Procedure

Following a procedure similar to that described in Example 3, but using 2.5 g of 2-amino-1-(3-methoxyphenyl)ethanol (prepared as described in Preparation 43), 4.0 g of methyl 4-(2-oxopropoxy)phenylacetate (prepared as described in Preparation 3), 80 ml of benzene, 60 ml of absolute methanol and 2.75 g of sodium cyanoborohydride, and then purifying the reaction product by column chromatography through silica gel, using ethyl acetate as the eluent, 3.11 g of the title compound were obtained having an Rf=0.21 (thin layer chromatography over silica gel, using ethyl acetate as the developing solvent).
