Methanesulfonyl chloride → HCID 54213645, compound

Participants

Reaction Steps

Into a solution of 6.7 g of 4-isopropylbenzohydroximoyl chloride in 175 ml of benzene was added in one portion 5.2 g of triethylamine. To this solution was added dropwise during 15 minutes (mildly exothermic reaction) 4.0 g of methanesulfonyl chloride. The mixture was stirred for 30 minutes and filtered. The filtrate was concentrated and the residue recrystallized twice from ethanol to give 8.1 g of N-(methanesulfonyloxy)-4-isopropylbenzimidoyl chloride, m.p. 79.5°-82°. The ir spectrum was consistent with the assigned structure.
