実験手順
A solution of 4,5-dimethylthiazole (2,2 g, 19.4 mmol) and 2-bromoacetylthiophene (4 g, 19.4 mmol) in ethyl alcohol (20 mL) was refluxed for 3 hours. It was cooled to room temperature and t-butyl methyl ether (10 mL) was added. The reaction mixture was left at room temperature overnight with stirring. The white product separated and was filtered and dried. It was crystallized from ethyl alcohol (4.42 g, 73%), m.p. 203-205° C.
