Procedure

A solution of 3-[4-[2-(1-piperidinyl)ethoxy]benzoyl]-2-[4-[2-(1-pyrrolidinyl)ethoxy]phenyl]benzo[b]thiophene-6-carboxamide (Part E) (131 mg, 0.219 mmol) in EtOAc (8 mL) was treated with a solution of oxalic acid (49.3 mg, 0.548 mmol) in EtOAc (8 mL) to form a white suspension. After filtration and drying, 135 mg (79%) of the title compound was obtained as a white solid.
