Reaktionsschritte

To a solution of benzylamine (5 g, 4.67 mmol) in pyridine (25 ml) was added (cautiously) p-toluenesulphonyl chloride (10 g, 5.25 mmol). The deep red coloured solution was stirred at room temperature for 1 hour before being poured into water (80-100 ml). The oily precipitate which solidified on scratching was filtered and recrystallised from ethanol to give the title compound (10.98 g, 90% yield, m.p. 115°-116° C., (Lit.1 114° C.)). δH (CDCl3): 7.80(2H,m); 7.25(7H,m); 4.95(1H,t); 4.05(2H,d); 2.35(3H,s)ppm.
