Versuchsvorschrift

A procedure similar to that described in Example 2 was repeated, except that 4.3 g of 2-amino-1-(3-chlorophenyl)ethanol (prepared as described in Preparation 8), 3.5 g of methyl 3-[4-(2-oxopropoxy)phenyl]propionate (prepared as described in Preparation 5), 150 ml of benzene, 150 ml of absolute methanol and 6.12 g of sodium borohydride were used. A crude product was obtained, and this was purified by column chromatography through silica gel, using a 10:1 by volume mixture of ethyl acetate and ethanol as the eluent, to give 2.9 g of the title compound having an Rf=0.40 (thin layer chromatography over silica gel, using a 10:1 by volume mixture of ethyl acetate and ethanol as the developing solvent).
