Reaction Steps
4-Iodobenzenesulfonyl chloride (604 g, 2 mol) was added with stirring to a solution of 4-methylphenol (227 g, 2.1 mol) and triethylamine (222 g, 2.2 mol) in toluene (1.5 l). The suspension was stirred at 60° C. for 2 h. The reaction mixture was added to excess dilute hydrochloric acid. The precipitate was filtered off and washed with ethanol. A second crop was obtained by concentrating the toluene mother liquor and collecting the solid material in the same manner. The combined crops were recrystallized from 2-propanol (2.5 l). Yield 680 g, 91%.
