Reaction Steps

To a solution of 5-chloro-2-(3,5-dimethyl-piperidin-1-yl)-benzonitrile (1.05 g, 4.220 mmol) in Diethylene glycol monomethyl ether (2.50 mL) was added KOH (0.947 g, 16.883 mmol) and water (0.750 ml). The reaction was heated at 130–135° C. overnight. Upon cooling to rt, water and ethyl acetate was added the organic layer was discarded and the aqueous layer is acidified to pH˜6–7. The aqueous layer was then extracted with ethyl acetate three times. The combined organic layer was washed with water, brine, dried (Na2SO4), and concentrated to give required 5-chloro-2-(3,5-dimethyl-piperidin-1-yl)-benzoic acid (0.850 g, 75%) as an off white solid. LCMS 268(M+1)+.
