実験手順

Zinc cyanide (4 g) and Pd(PPh3)4 (1.16 g) were added to a DMF (60 mL) solution of methyl 2-phenyl-6-{[(trifluoromethyl)sulfonyl]oxy}pyridine-4-carboxylate (3.7 g), and stirred at 90° C. for 3 hours. The reaction liquid was filtered through Celite, the solvent was partly evaporated away, the residue was diluted with ethyl acetate, water was added to it, and the solution was extracted with ethyl acetate. The organic layer was washed with water and saturated saline water, dried with anhydrous sodium sulfate, filtered and the solvent was evaporated away. The residue was purified through silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound as a yellow powder.
