実験手順
Cyclopentanol (50.0 g, 0.58 mol) and p-toluenesulfonyl chloride (120 g, 0.629 mol) were dissolved in pyridine (200 ml), and the solution was poured into ice-water (about 1 liter), followed by thoroughly stirring. The precipitated solid was filtered and dried to obtain cyclopentyl p-toluenesulfonate as a white solid (94.9 g, 0.390 mol, 68.1% yield).
