Toluene → HCID 18504640, compound

Participants

Reaction Steps

A mixture of 4.0 g of 2-(3-hydroxypropyloxy)-5-trifluoromethylpyridine, 3.4 ml of triethylamine and 25 ml of toluene was vigorously stirred under a nitrogen stream, while cooling in chilled water bath to 5° C. Then, 1.63 g of methanesulfonyl chloride was added dropwise to this mixture at such a rate that the reaction temperature did not exceed 10° C., and the chilled water bath was removed. After further stirring continued at room temperature for 1.5 hours, 250 ml of water was added thereto, and the mixture was vigorously stirred for further 30 minutes, followed by phase separation. The toluene layer was washed once with water, dried with magnesium sulfate, and concentrated, which afforded 5 g of 2-(3-methanesulfonyloxypropyloxy)-5-trifluoromethylpyridine as an oily product (92% yield).
