Procedure

Following a procedure similar to that described in Example 3, but using 3.0 g of 2-amino-1-(3-chloro-4fluorophenyl)ethanol (prepared as described in Preparation 40), 4.22 g of methyl 4-(2-oxopropoxy)phenylacetate (prepared as described in Preparation 3), 80 ml of benzene, 60 ml of absolute methanol and 3.5 g of sodium cyanoborohydride, and then purifying the reaction product by column chromatography through silica gel, using ethyl acetate as the eluent, 3.31 g of the title compound were obtained having an Rf=0.22 (thin layer chromatography over silica gel, using ethyl acetate as the developing solvent).
