Reaktionsschritte

To a stirred suspension of 11.4 g of lithium aluminum hydride in 500 ml of dry diethyl ether, 32.7 g of ethyl 6-methylnicotinate in 250 ml of dry diethyl ether is added dropwise at room temperature, and the mixture is refluxed for 1.5 hours. The reaction mixture is cooled to 0° C., and the remaining lithium aluminum hydride is decomposed by the cautious addition of 60 ml of water. The ether layer is decanted, and the residual solid is extracted with three 150-ml portions of diethyl ether. The combined extracts are dried over potassium carbonate and concentrated to give 19.6 g of crude 5-hydroxymethyl-2-methylpyridine.
