By essentially following the conditions described in Example l, Part F, the free base of the title compound was prepared as a foam from 2-(4-aminophenyl)-3-[4-[2-(1-pyrrolidinyl)ethoxy]benzyl]benzo[b]thiophene (Example 16; Part D) and (−)-2-oxo-4-thiazolidinecarboxylic acid in 67% yield following radial chromatography (SiO2; 1% then 2% then 4% MeOH in CHCl3 sat'd with NH4OH). The product was converted to the oxalate salt according to the proceedure described in Example 1, Part G.
