A mixture of 2-fluoro-6-(piperidin-4-ylmethoxy)-benzonitrile hydrochloride (200 mg; 0.7 mmol) (Example 126, Step 3) was stirred at room temperature with 2-chlorobenzoyl chloride (129 mg; 0.7 mmol) and triethylamine (0.3 mL; 2.1 mmol) for 16 hours. Reaction was cooled and quenched with dilute HCl and mixture extracted with ethyl acetate (2×20 mL). Combined organics washed with water, saturated sodium bicarbonate, brine and dried over Na2SO4. Crude material was purified by chromatography using 0.5-2% methanol/DCM gradient to afford 2-[1-(2-chloro-benzoyl)-piperidin-4-ylmethoxy]-6-fluoro-benzonitrile as a white solid. (225 mg; 86% yield).
