Potassium Carbonate → N-cyclohexyl-N-(pyridin-3-ylmethyl)-methanesulfonamide

Participants

Reaction Steps

A 2.85 g. portion of 3-cyclohexylaminomethylpyridine was dissolved in 15 ml. of dichloromethane, and 2.8 g. of potassium carbonate and 1.6 ml. of methanesulfonyl chloride were added. The mixture boiled vigorously for a short time, and was then stirred at ambient temperature overnight. The mixture was diluted with 25 ml. of additional dichloromethane, and was extracted with 20 ml. of water and dried over magnesium sulfate. The organic solution was reduced in volume and chromatographed over silica gel, eluting first with dichloromethane and then with 9:1 dichloromethane:ethyl acetate. The product-containing fractions were evaporated under vacuum, and the residue was triturated with petroleum ether and diethyl ether to obtain 0.8 g. of the desired product.
