Diethyl Ether → 4-(2-Methylbenzoyl)pyridine

참여 물질

반응 단계

Pyridinium chlorochromate (9.29 g, 43.1 mmol) was dissolved in dichloromethane (50 ml) and a solution of 2-methylphenyl-(4-pyridyl)methanol (5.72 g, 28.7 mmol) in dichloromethane (30 ml) was added. The reaction mixture became dark immediately, and was stirred for 2 h at room temperature. Diethyl ether (350 ml) was added, and the reaction mixture was filtered through "hyflo" and evaporated to a dark oil (11.26 g). Flash chromatography on silica gel (Merck Art 9385) eluting with heptane/tetrahydrofuran (4:1) provided the title compound (2.74 g, 48%) as an oil. T.l.c. rf=0.45 (SiO2, ethyl acetate).
