Preparation of 3-cyano-4-methylpyridine
Alternative Names: 4-methylnicotinonitrile; 3-Cyano-4-picoline; 4-methylpyridine-3-carbonitrile; 4-methyl-nicotinonitrile;
A mixture of 1 equiv. of 4-methylpyridine-3-carbaldehyde and 1.1 equiv. of hydroxylamine hydrochloride are mixed with the dimethylsulfoxide until the homogeneous mixture is obtained (3-5 volumes) and the obtained mixture is stirred at 90° C for 1-2 hours. The reaction is monitored by TLC (ethyl acetate:hexane 5:95) and when is completed the mixture is cooled and poured in water, the reaction product is extracted with ether, dried and the ether is removed by evaporation affording 96% of the 3-cyano-4-methylpyridine.
