Reaktionsschritte

Potassium tert-butoxide (478 mg, 0.00426 moles) was added to a solution of 1-(3-iso-propyl-1,2,4-oxadiazol-5-yl)piperidin-4-ol (0.9 gm, 0.00426 moles) and 4,6-dichloro-5-methylpyrimidine (690 mg, 0.00426 moles) in dry THF (30 ml) at 0° C. and the reaction mixture was stirred for 20 hours at 30° C. The reaction mixture was poured into ice cold water and extracted with ethyl acetate. The organic extract was successively washed with water & brine, dried over sodium sulfate and evaporated under reduced pressure to yield 900 mg product as off white solid.
