Procedure
At 0° C., 25 ml of DMF and 3.25 g (28 mmol) of potassium tert-butoxide were initially charged and mixed with 2.5 g (27.5 mmol) of 3-hydroxytetrahydrofuran. The solution was cooled to −15° C., and 4.7 g (140 mmol) of 3-bromomethyl-2-chloro-4-methylsulfonylbenzoic acid were added. The mixture was then stirred at 15-20° C. for one hour. The reaction was poured into 45 g of ice/water, acidified with 2N HCl and extracted with EA. The organic phases were dried with MgSO4, filtered and concentrated. This gave 5.41 g of a viscous oil of a purity of about 66% according to HPLC. Yield about 60%
