Procedure

To a solution of 15.25 g (107.24 mmol) 4-(2-hydroxyethyl)cyclohexanone in 115 mL of dichloromethane cooled at a temperature close to 0° C., is added 18 mL (129.5 mmol) of triethylamine, then 9.25 mL (119.50 mmol) of mesyl chloride. The mixture is stirred for two hours at room temperature. Water (120 mL) is added. The organic phase is separated by decantation, washed with a saturated aqueous solution of sodium hydrogenocarbonate (100 mL), dried over magnesium sulfate and concentrated under reduced pressure to give 28 g of 4-(2-hydroxyethyl)cyclohexanone mesylate used without further purification in the next step.
