実験手順
A solution of 1.01 g (0.0079 mol) of 1,3-dimethylimidazolin-2-thione (prepared by the procedure Of B.L. Benac et al, Org. Syn. 64, 92 (1985) in 40 mL of acetone was added dropwise to a solution of 1.0 g (0.0079 mol) of 1,3-dichloropropanone in 50 mL of acetone over 2 hours. The resulting solution was stirred at room temperature for 18 hours whereupon a precipitate formed. The latter was removed by filtration and dried to obtain 1.76 g (87%) of 1,3-dimethyl-2-[(3-chloro-2-oxopropyl)thio]-1H-imidazolium chloride, m.p. 157-158° C.
