This compound has unique chemical properties. The synthetic route is as follows. Safety of 1-(4,6-Dimethylpyridin-2-yl)ethanone
At room temperature, a solution of 2.05 g (2.0 mmol) of 2-acetyl-5,6-dimethylpyridine (II-1) in 50 ml of ethanol and 30 mg of p-toluenesulphonic acid were added to a solution of 0.53 g (2.0 mmol) of (1E)-1-(5,6-dimethylpyridin-2-yl)ethanone O-({1-[(aminooxy)methyl]cyclopropyl}methyl)oxime (XII-8) in 10 ml of ethanol, and the mixture was heated under reflux for 4 h. After cooling, the reaction mixture was poured into ice-water and neutralized by addition of triethylamine. After extraction with dichloromethane, the combined organic phases were dried over Na2SO4 and freed from the solvent under reduced pressure. Purification by column chromatography on silica gel using cyclohexane/ethyl acetate gave 0.73 g (1.6 mmol, 79% of theory) of (1E)-1-(4,6-dimethylpyridin-2-yl)ethanone O-({1-[({[(1E)-1-(5,6-dimethylpyridin-2-yl)ethylidene]amino}oxy)methyl]cyclopropyl}methyl)oxime of logP (HCO2H)=2.61.
