실험 절차
To a 0° C. solution of 23.8 g of benzyl alcohol, 0.05 g of 4-(dimethylamino)pyridine, 18.3 g of pyridine and 250 ml of methylene chloride is added, dropwise, a solution of 29.5 g of racemic 2-methyl-4-pentenoyl chloride in 50 ml of methylene chloride. The mixture is stirred at room temperature for 4 hours, followed by successive washing with 2N hydrochloric acid, saturated sodium bicarbonate and saturated sodium chloride. The organic layer is dried and concentrated in vacuo. The residue is purified by Kugelrohr distillation to give 35.2 g of the desired product as a colorless oil; bp 70°-75° C. at 0.10 mm Hg.
