Versuchsvorschrift

A mixture of 2-fluoro-6-(piperidin-4-ylmethoxy)-benzonitrile hydrochloride (200 mg; 0.7 mmol) (Example 123, Step 3) was stirred at room temperature with 4-iodobenzoyl chloride (187 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 0.5-1% methanol/DCM gradient to afford 2-[1-(4-iodo-benzoyl)-piperidin-4-ylmethoxy]-6-fluoro-benzonitrile as a white solid. (273 mg; 84% yield).
