Procedure
A solution of methyl 4-bromo-2-(isopropylsulfonyl)benzoate (Intermediate 242; 516 mg; 1.61 mmol) in THF (10 ml) was treated with a 5 N solution of NaOH in water (4 mL) and the reaction mixture was heated at 60° C. for 1 day. The reaction mixture was acidified with aqueous HCl and the reaction mixture was extracted 3 times with EtOAc. The combined organic phases were dried over MgSO4, filtered and concentrated to dryness affording the title compound as a pale yellow solid (386 mg; 78%).
