Mode opératoire

In 100 ml of acetonitrile was dissolved 11.8 g of tetrahydrothiophene, to the solution was gradually added 20 g of 1-bromo-3,3-dimethyl-2-butanone. The mixture was stirred at room temperature for 2 days to deposit powder. After adding 100 ml of ethyl acetate to the reaction solution, the powder was collected by filtration, washed with ethyl acetate and dried to obtain 24 g of 2-oxo-3,3-dimethylbutyltetrahydrothiophenium bromide.
