실험 절차
To a solution of 1-(4-allyloxycarbonyl-1,3-thiazol-2-yl)-3-methanesulfonyloxyazetidine (2.70 g, 8.51 mmol) (obtained as described in Reference Example 41(3)) in dimethylformamide (135 ml) was added potassium thioacetate (5.83 g, 51.1 mmol) at room temperature. The mixture was stirred in an oil bath (80° C.) for 10 hours. After checking the completion of the reaction, the reaction mixture was partitioned between ethyl acetate and 10% aqueous sodium chloride solution. The organic layer was washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by chromatography on a silica gel column using n-hexane:ethyl acetate (2:1) as the eluant to afford 3-acetylthio-1-(4-allyloxycarbonyl-1,3-thiazol-2-yl)azetidine (1.61 g, yield 63%) as a pale brown solid.
