Reaction Steps
A mixture of 10.0 g of 2-[2-(4-methoxycarbonylmethylphenoxy)-1-methylethyl]amino-1-(3-chlorophenyl)ethanol (prepared as described in Example 3) and 2.8 g of fumaric acid was dissolved in methanol and then the methanol was removed by distillation under reduced pressure. The residue was recrystallized from ethyl acetate, to give 11.5 g of the title compound as crystals, melting at 130°-146° C.
