실험 절차

To methanol (5 ml), 1-[2-(2,4-dimethylphenyl)-4-methylthiazol-5-yl]ethanone (981 mg) prepared in the Step 31-1-1 was added, and a solution of potassium hydroxide (673 mg) in methanol (10 ml) was added dropwise thereto under cooling by ice and stirring. Thereafter, iodobenzene diacetate (1.42 g) was added to the mixture, and then the resulting mixture was stirred at a room temperature for 22 hours. From the mixture methanol was distilled off under a reduced pressure, and water was added to the residue. The resulting mixture was subjected to extraction with dichloromethane. The extract was dried over anhydrous sodium sulfate, and then dichloromethane was distilled off under a reduced pressure. Hexane was added to the residue, the precipitate was separated by filtration, washed with hexane, and then dried under a reduced pressure to give the title compound (328 mg, 26%).
