実験手順

5-Acetyl-2,4-dimethylthiazole (2.5 g) in dry diethylether (10 ml) was added dropwise to a stirred solution of 3-lithiopyridine (from 3.5 g 3-bromopyridine) in diethylether at -70° C. After 3 hours the mixture was allowed to warm to room temperature. After a further 1 hour, aqueous sodium hydrogen carbonate was added and the organic layer was separated. The aqueous layer was extracted with diethylether. The material obtained from the combined organic layers was purified by flash chromatography to give the title compound, m.p. 107.5°-109° C.
