Procedure

2-Methanesulfonyloxyundecane was prepared as described for 2-methanesulfonyloxydecane from 2-undecanol (30.0 ml, 144 mmol), methanesulfonylchloride (15.5 ml, 200 mmol) and diisopropylethylamine (30.8 ml, 177 mmol) in dry CH2Cl2 (240 ml). After stirring for 3.5 hrs, the reaction was processed as previously stated but at 4 times the volumes to provide 2-methanesulfonyloxyundecane (31.35 g, 95%).
