[(1R,2R)-2-(methylsulfonyloxymethyl)cyclohexyl]methyl methanesulfonate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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). cooling The reaction mixture is washed with water dried concentrated under reduced pressure Diethyl ether is added to the residue for crystallization the precipitated crystals are collected

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The thus obtained compound (2) (5.1 g; 35.4 mmol) is dissolved in triethylamine (10.37 g; 103 mmol) and acetonitrile (127 ml), and methanesulfonyl chloride (8.13 g; 71 mmol) is dropwise added thereto under ice-cooling. The resultant mixture is ice-cooled for 1 hour and allowed to react at room temperature for 3 hours. The reaction mixture is washed with water, dried and concentrated, followed by addition of diethyl ether. Precipitated crystals are collected by filtration to give trans-1,2-bis(methanesulfonyloxymethyl)cyclohexane (3) (5.4 g). under ice-cooling cooled for 1 hour to react at room temperature for 3 hours The reaction mixture is washed with water dried concentrated followed by addition of diethyl ether Precipitated crystals are collected by filtration

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
