Dimethyl Disulfide → HCID 13154244, compound

Participants

Reaction Conditions

Reaction Steps

A solution of 2-tert-butylcarbonylamino-4-picoline (Step A, 250 mg) in anhydrous ethyl ether (5 mL) was cooled to -78° C. and treated with tert-butyllithium (1.7 mL, 1.7 M), and stirred at -78° C. for 3 hrs. To this was added dimethyl disulfide (0. 177 mL) and the reaction was allowed to warm to room temperature. The mixture was diluted with water and ethyl ether. The aqueous layer was extracted with ether. The combined organic layers were washed with saturated sodium chloride, dried over sodium sulfate, and concentrated in vacuo. The resulting oil was purified by medium pressure liquid chromatography on a 21×300 mm silica column eluted with 40% ethyl acetate/methylene chloride to afford the title compound (260 mg, lower Rf spot) and 2-tert-butylcarbonylamino-4-methylthiomethylpyridine (40 mg, higher Rf spot).
