Reaction Steps

A mixture of 12.8 g. of 3-[p-(benzyloxy)phenyl]propanol O-methanesulfonate (prepared as described in Example 43), 50 ml. of hexamethylphosphoramide and 16.5 g. of ethyl p-aminobenzoate is heated at 100°-105° C. for 17.5 hours. The mixture is chilled, diluted with 15 ml. of water, 30 ml. of ethanol and chilled. In order to filter, 100 ml. of ethanol-water (1:1) is added and the solid filtered and washed with ethanol-water (1:1) and with water to give tan crystals, m.p. 98°-107° C. Recrystallization from ethanol gives light tan crystals, m.p. 114°-116° C.
