To a mixture of 2-fluoro-benzonitrile (1.6 g, 13.2 mmol) and 1-methyl-piperidin-4-ol (1.52 g, 13.2 mmol) in dioxane (50 mL) was added NaH (60%)(634 mg, 15.8 mmol) in portion. The reaction was heated at 50° C. overnight. The mixture was poured into water, and extracted with ethyl acetate (2×). The solvent was removed, and the resulting residue was chromatographered using ethyl acetate/methanol (20:1-10:1) to give the title compound (870 mg, 31%).
