実験手順
To a solution of nitromethane (2.31 ml) in methanol (5.4 ml) was added sodium (70 mg) at ice-cooled temperature. The resulting mixture was added dropwise to a solution of 1-(4-pyridyl)-4-piperidone (5.36 g) in methanol (10.7 ml) at ice-cooled temperature for 10 minutes, and stirred for 15 hours at room temperature. The precipitate was filtered, and washed with methanol to obtain the title compound (5.31 g).
