Procedure

N,N-Dimethylethylenediamine (0.87 mL, 7.9 mmol) was added to a solution of 4-methanesulfonyloxymethylbenzoic acid benzyl ester (Reference Compound No. 7-1, 2.3 g, 7.2 mmol) and triethylamine (3.0 mL, 22 mmol) in DMF (10 mL), and then the reaction mixture was stirred at room temperature for 2 hours. Saturated aqueous sodium hydrogen carbonate solution (150 mL) was added thereto, and then the whole was extracted with chloroform (100 mL) three times. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure to give 1.2 g of a mixture, which contains the title reference compound as yellow oil.
