Conditions

Temperature
130 °C

Procedure

Octadecyl parachlorobenzenesulfonate (11.1 g) was added to 5.13 g of 5-methoxy-2-methylbenzoselenazole, and the mixture was heated at 130° C. for 5 hours. The crystals yielded by the reaction were washed with ether and then recrystallized from benzene to give 9.98 g of 5-methoxy-2-methyl-3-octadecylbenzoselenazolium parachlorobenzenesulfonate (yield 67%).
