Reaction Steps
3,4-Dichloro-5-ethoxycarbonylisothiazole (6.0 g, 0.027 mol) and 4 ml of methyl fluorosulfonate were heated at 110° for 1 hr under a nitrogen atmosphere. The solid was washed with ether and benzene to yield 9.0 g (99%) of 3,4-dichloro-2-methyl-5-ethoxycarbonylisothiazolium fluorosulfonate, mp 118-123. Analysis--Calculated for C7H8Cl2FNO5S2 : Cl, 20.84; N, 4.12; S, 18.85. Found Cl, 20.56; N, 4.06; S, 18.89.
