Triethylamine → HCID 23206165, compound

Participants

Reaction Steps

4.25 g (10 mmol) of 2,4-bis-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethylethyl)-toluene were dissolved in 50 ml of methylene chloride, and 2.5 g (25 mmol) of triethylamine were added. 2.86 g (25 mmol) of methanesulfonyl chloride were added dropwise at 5° to 10° C. The mixture was stirred for 16 hours at room temperature, separated off from the precipitated salt, washed with water, dried and evaporated down. The residue was chromatographed over a silica gel column with methylene chloride/n-hexane (1:1). After the eluate had been evaporated down, 2.9 g of 2,4- bis-(2,2,2-trifluoro-1-methanesulfonyloxy-1-trifluoromethylethyl)-toluene were obtained (colorless crystals, m.p.: 107° C.).
