Sulfuryl chloride → HCID 21411861, compound

Participants

Reaction Steps

To a stirred suspension of 215.4 g. (0.865 moles) of the product of Example IV in 4 liters of dichloroethane at 0° C. is added dropwise 116.8g. (0.865 moles) of freshly distilled sulfuryl chloride. After addition is complete (about 40 minutes), the reaction mixture is allowed to warm to ambient temperature and is stirred for about 4 hours, after which the solvent is evaporated to give a tan residue. Recrystallization of this residue from dichloroethane/ether gives 1-(4-chloropyrrol-2-ylmethylene) pyrrolidinium perchlorate; m.p. 122°-126° C.
