Synthesis of benzyl p-toluenesulfonate

Preparation of benzyl p-toluenesulfonate

22g of tosyl chloride were dissolved in 88 ml of dry pyridine (the temperature rising from 22°C to 24°C), and the solution was cooled to -10°C. 10.9 ml of absolute benzyl alcohol were added, the temperature rising to -5°C after 2 minutes and then falling to – 10°C. Crystallization commenced after a further 3 minutes, and the mixture was kept at -10°C for 15 minutes more. Sulfuric acid (280 ml of 5N, cooled to 0°C) was added rapidly, with cooling. The crystalline product was washed with heptane and water, and dried; yield, 10.5 g.; m.p. 55°C.
