To a stirred solution of mofezolac (500 mg, 1.47 mmol) in dry CH2Cl2 (25 mL) , kept at 0C by an ice-bath, HOBt monohydrate (253 mg, 1.48 mmol) and EDC hydrochloride (303 mg, 1.58 mmol) were added. Separately a stirred solution of methyl 11-aminoundecanoate hydrochloride (370 mg, 1.38 mmol) in dry CH2Cl2 (13 mL) was mixed with DIEA (0.45 mL, 2.6 mmol) at room temperature. After 2h, this solution was dropwise added to the reaction mixture and stirred overnight at room temperature. Then, sat. aq. NaHCO3 was added and the aqueous solution extracted three times with EtOAc. The combined organic layers were dried over anhydrous Na2SO4, and the solvent distilled under reduced pressure.
