Procedure

To a solution of methyl 4-(2-amino-5-chlorophenylmethoxy)benzoate (450 mg; prepared in Reference Example 10.) in methylene chloride (4 ml), pyridine (0.24 ml) and 4-chlorobenzenesulfonylchloride (380 mg) were added. The mixture was stirred for 21 hour. To the reaction mixture, water was added. The mixture was extracted with ethyl acetate. The organic layer was washed, dried over and concentrated under the reduced pressure. The residue was purified by recrystallization from hexane-AcOEt mixture solvent to give the title compound (310 mg) having the following physical data.
