실험 절차

To a solution of (R)-methyl 4-(1-hydroxybutyl)benzoate, intermediate (26) (10 g, 48 mmol) in methyl t-butyl ether (80 mL) containing triethylamine (6.32 g, 62 mmol) was added methanesulfonyl chloride (6.05 g, 53 mmol) slowly at 20° C. The solution was filtered to remove triethylamine salts and the solution used in the next step without isolation.
