Procedure

To a solution of methyl 5-chloro-2-[(2-chlorophenoxy)methyl]benzoate (step 1, 103 mg, 0.33 mmol) in methanol (4 mL) and tetrahydrofuran (4 mL) was 2 N sodium hydroxide (1 mL) and the mixture was stirred at room temperature for 16 hours. After removal of solvent, the residue was diluted with water (5 mL) and the solution was acidified with 2 N hydrochloric acid. Precipitate was collected by filtration, washed with water and dried in vacuo to afford 85 mg (86%) of the title compound:
