Following a procedure similar to that described in Example 6, but using 5.15 g of 2-amino-1-(3-chlorophenyl)ethanol (prepared as described in Preparation 8), 10.3 g of methyl 3-chloro-4-(2-oxopropoxy)phenylacetate (prepared as described in Preparation 19), 200 ml of benzene, 100 ml of absolute methanol and 6 g of sodium cyanoborohydride, 1.2 g of the title compound were obtained as crystals, melting at 83°-103° C. (after recrystallization from a mixture of ethyl acetate and hexane).
