Reaction Steps

To a solution in DMF (50 mL) of 3-hydroxypyridine (4.76 g, 50 mmol) was added 1,1-diazabicyclo[2.2.2]octane (6.80 g, 150 mmol) and dimethylthiocarbamoyl chloride (18.5 g, 150 mmol) and the reaction mixture was stirred for 0.5 hours at ambient temperature and 18 hours at 55° C. The reaction mixture was cooled to ambient temperature and poured into ether. The ethereal solution was washed with aqueous 2N sodium hydroxide (2×), water (2×) and brine, dried, filtered and concentrated in vacuo. Chromatography on silica gel (1:1 ethyl acetate-hexane) gave 3-dimethylthiocarbamoylpyridine (5.46 g).
