YieldReaction ConditionsOperation in experiment
With ammonium chloride; In diethyl ether; ii) Production of 1-(4-chloro-6-methyl-2-pyridinyl)ethanone 10 g (66 mmol) of <strong>[104711-65-1]4-chloro-2-cyano-6-methylpyridine</strong> was dissolved in 100 ml of anhydrous diethyl ether. The resultant solution was cooled to maintain the temperature thereof at 5 C., and was then fed dropwise with 262 ml (87 mmol) of diethyl ether solution of 3M-methyl magnesium bromide (manufactured by Aldrich) at the same temperature in a manner of spending 15 min. At that time, the inner temperature of the mixture had elevated to 20 C. due to heat generated by the reaction. The mixture was stirred for 2.5 hours, then cooled down to 5 C. and added with aqueous solution of ammonium chloride to discontinue the reaction. The reacted mixture was extracted with diethyl ether, and the resultant nonaqueous layer was washed with water, then dried with anhydrous magnesium sulfate and condensed under reduced pressure to thereby obtain a crude product. The obtained crude product was purified by means of silica gel column chromatography (elude; hexane:ethyl acetate=4:1 (v/v)) to obtain the target compound in an amount of 3.8 g. 1H-NMR (CDCl3, TMS, delta ppm) data; 2.61 (s, 3H), 2.70 (s, 3H), 7.32 (d, 1H), 7.83 (d, 1H).
