Procedure

2-Methylbenzoselenazole (10.1 g ) was dissolved in 100 ml of chloroform, then 10.0 g of methyl iodide was added to the solution, and the mixture was heated in an autoclave at 80° C. for 5 days. The crystals resulting from the reaction were taken out by filtration, washed with ether and dried to give 16.4 g of 2,3-dimethyl-benzoselenazolium iodide (yield 94%).
