Thionyl Chloride → HCID 86584468, compound

Participants

Reaction Steps

A mixture of 6.9 g (20 mmol) of methyl 2-chloro-3-(1′-hydroxy-2′,2′-dimethylethylaminocarbonyl)-4-methylsulfonylbenzoate and 5 ml of thionyl chloride was stirred for 6 hours at room temperature. The solution was diluted with 50 ml of dichloromethane and subsequently concentrated. The residue was dissolved in 20 ml of dichloromethane. The addition of cyclohexane resulted in a crystalline precipitate which was filtered off with suction and dried. This gave 6.4 g (88% of theory) of methyl 2-chloro-3-(1′-chloro-2′,2′-dimethylethylaminocarbonyl)-4-methylsulfonylbenzoate.
