To a solution of 2-(chlorosulfonyl)acetyl chloride (1 g, 5.65 mmol) in dry Et2O (5 ml) cooled to 0° C., a solution of methanol (0.286 g, 6.21 mmol) in dry Et2O (1 ml) was added dropwise. After 15 minutes, the mixture was warmed to RT and stirred for 2 hours. The solvent was evaporated and the desired compound was obtained (1 g, 5.36 mmol, 95% yield) and used in the next step without further purification.
