실험 절차

A mixture comprising 26.8g (0.2 mole) of 1,3-dithiol-2-thion and 25.2g (0.2 mole) of dimethylsulfuric acid was reacted at 60° C for 30 minutes and then at 90° C for 30 minutes. After cooling, the reaction product was poured into 150 ml of a saturated aqueous sodium perchlorate solution to deposit crystals. The crystals were recovered by filtration, washed with ether, dried and then recrystallized from methanol to obtain 42.5g of yellow crystals, m.p. 42°-46° C, yield 85.8%.
