실험 절차

To a cold solution of 166 g of 4-hydroxy-1-octyne [Prostaglandins, 10, 289 (1975)], and 240 g of imidazole in one liter of dimethylformamide is added dropwise 202 g of chlorotrimethylsilane. The mixture is allowed to stand at room temperature for 2 to 3 days. The mixture is partitioned with water and hexane. The hexane layer is washed with brine dried over magnesium sulfate, and concentrated. Distillation of the residue gives a colorless liquid, bp 38° C. (0.2 mm).
