To a solution of 6-methylpyridin-3-ol (0.5 g, 4.6 mmol) in toluene (6 mL) was added (1-methylcyclopropyl)methanol (0.59 g, 6.9 mmol) and stirred under nitrogen atmosphere. The solution was added cyanomethylenetri-n-butylphosphorane (CMBP, 2.5 ml, 9.53 mmol) and stirred at 100° C. for 3 hours. The reaction mixture was evaporated. The residue was purified by column chromatography on silica gel eluting with hexane/ethyl acetate (2:1 (v/v)) to give 820 mg (quantitative yield) of the title compound as a brown oil:
