Reaction Steps

To a mixture of 6 g of 2-benzylthio-6-ethylaminopyridine and 60 ml of tetrahydrofuran was added dropwise 17.3 ml of a 1.65 mol/l hexane solution of n-butyl lithium at -10° to 0° C. in a nitrogen stream. To the reaction mixture was added 3.4 g of methysulfonyl chloride at 0° to 15° C., followed by reacting for 0.5 hour. After completion of the reaction, the reaction mixture was poured into water, made weakly acidic with hydrochloric acid, and extracted with methylene chloride. The extract was dried over anhydrous sodium sulfate, followed by concentration under reduced pressure. The residue was purified by silica gel column chromatography (developing solvent; ethyl acetate/hexane=1/19 by volume) to obtain 3.4 g of N-(6-benzylthiopyridine-2-yl)-N-ethylmethylsulfonamide as an orange crystal.
