Procedure

Tert-butyl-4-hydroxyphenylcarbamate (1.0 g, 4.78 mmol) and triethylamine (0.80 mL, 5.73 mmol) were combined in dichloromethane (50 mL), cooled in an ice bath and treated with methanesulfonyl chloride (0.41 mL, 5.26 mmol). The solution was stirred at ambient temperature for 2 h, then was washed with 1M HCl, dried over sodium sulfate, filtered, and concentrated to give 1.2 g (87%).
