Procedure

To a solution of 3-(5-piperidin-4-yl-[1,3,4]oxadiazol-2-yl)-5-p-tolyl-pyridin-2-ylamine (250 mg, 0.746 mmol) in THF (25 mL) was added NaH (55%) (48.8 mg, 1.119 mmol) at 0° C. The reaction mixture was stirred at 0° C. for 1 h. Then MeI (95 mg, 0.671 mmol) was added at 0° C., and the reaction mixture was stirred at 0° C. for a further 3 h. The reaction mixture was then poured into ice-water (30 mL) and extracted with ethyl acetate (3×20 mL). The organic layer was washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure to afford crude compound. Crude compound was purified by preparative HPLC to afford the title compound as a pale yellow solid.
