実験手順
A 1.5 M solution of methyllithium in diethyl ether (6.0 ml) dissolved in diethyl ether (15 ml) was treated dropwise with a solution of 4-chloropyridine-2-carboxylic acid in diethyl ether (15 ml) under an argon atmosphere, and stirred at room temperature for 2 hours. The reaction mixture was diluted with a saturated solution of ammonium chloride and diethyl ether, and the organic phase was washed with brine, dried and concentrated. The resultant residue was purified by a column chromatography on a silica gel (ethyl acetate:methanol=20:1) to obtain the title compound (459 mg) as a tan oil.
