Sulfuryl chloride → HCID 20146207, compound

Participants

Reaction Steps

2-(2-Tetradecyloxyphenyl)carbamoyl-1-naphthol (22.8 g) was dissolved in 100 ml of dichloromethane, and a dichloromethane solution of sulphenyl chloride prepared from 25 g of 1-(3-ethoxycarbonylphenyl)-5-mercaptotetrazole and 13.5 g of sulfuryl chloride was added dropwise thereto at room temperature. The resulting dichloromethane solution was stirred for an additional 5 hours, and washed with an aqueous sodium bicarbonate solution and further with water. The dichloromethane was distilled away under reduced pressure and the residue was crystallized from methanol to obtain 26.9 g of 2-(2-tetradecyloxyphenyl)carbamoyl-4-[1-(3-ethoxycarbonylphenyl)-5-tetrazolylthio]-1-naphthol, m.p., 88°-90° C. Yield was 74.3%.
