Procedure

Phenacyl bromide, 88.2 g (0.44 mole) and tetrahydrothiophene, 39.1 g (0.44 mole) were dissolved in 220 g of nitromethane, which was stirred for 4 hours at room temperature. The reaction solution was combined with 800 g of water and 400 g of diethyl ether. The aqueous layer separated was taken out, which was an aqueous solution of the target compound, phenacyltetrahydrothiophenium bromide.
