Allyl bromide → HCID 20335941, compound

Participants

Reaction Steps

A mixture of 50 g (0.156 mol) of 3,5-dimethyl-1-hexadecylpyrazole, 200 ml of sulfolane and 19 g (0.156 mol) of allyl bromide is stirred and kept at a temperature of 80° C. for 24 hrs. The reaction mixture is allowed to cool and 100 ml of ether are added. The mixture is stirred for another 2 hrs and the crystalate is then filtered off, washed with ether, and vacuum dired at 40° C./12 Torr. Recrystallization from 200 ml of ethyl acetate yields 39.6 g of 2-allyl-3,5-dimethyl-1-hexadecyl-pyrazolium bromide; m.p. 99°-100° C.
