실험 절차

A solution of (1S,2R,4aS,8aS)-1-(hydroxymethyl)-2,5,5,8a-tetramethyl-decahydronaphthalen-2-ol (3) (12 g, 50 mmol) in anhydrous DMF (100 mL) was cooled with an ice bath under N2. To this mixture, triethylamine (15 mL, 110 mmol) and methanesulfonyl chloride (5.0 mL, 60 mmol) was added. The ice bath was removed and the mixture stirred at room temperature for 3 h. The reaction was diluted with diethyl ether and washed with 1 M HCl, saturated aqueous sodium bicarbonate and brine. The organic layer was concentrated to dryness to yield [(1S,2R,4aS,8aS)-2-hydroxy-2,5,5,8a-tetramethyl-decahydronaphthalen-1-yl]-methyl methanesulfonate (12) (15 g, 97% yield) as an orange solid.
