Triethylamine → 1,2-Bis(methanesulfonyloxymethyl)cyclohexane, (1R,2R)-

Participants

Reaction Steps

To a solution of the compound (2) (71.86 g; 0.499 mol) and triethylamine (151.21 g; 1.497 mol) in chloroform (1 liter), methanesulfonyl chloride (114.27 g; 0.998 mol) is dropwise added under ice-cooling, and the resultant mixture is stirred at room temperature for 6 hours. The reaction mixture is washed with water, dried and concentrated under reduced pressure. Diethyl ether is added to the residue for crystallization, and the precipitated crystals are collected to give trans-1,2-bis(methanesulfonyloxymethyl)cyclohexane (3) (88.57 g).
