Reaction Steps
5-Chloro-2-(methylthio)-benzoxazole (Int-I) (19.9 g, 01 mol) and 18.7 g methyl p-toluenesulfonate were heated to 140°-150° C. for 2.5 hrs. Upon cooling to 60° C., acetone was added to cover and slurry. The product was collected by filtration, crushed, and slurried overnight in acetone. Filtration and drying yielded 21.37 g (56%), mp 145°-164° C.
