Procedure

By essentially following the conditions described in Example 179, Part A, the free base of the title compound was prepared as an oil from 2-(4-aminophenyl)benzo[b]thiophene-3-yl 4-[2-(1-pyrrolidinyl)ethoxy]phenyl ketone (Part C) in 85% yield following MPLC (SiO2; 30% then 40% THF with 5% TEA in hexanes). The product was converted to the oxalate salt according to the conditions described in Example 1, Part G.
