N-Diisopropyl-N-ethylamine (DIEA, 0.215 mL, 1.237 mmol) andmethyl 5-aminopentanoate hydrochloride (6) (100 mg, 0.60 mmol)were solubilized in anhydrous CH2Cl2 (5 mL) and stirred at 0 C for1 h. Then, this solution was dropwise added to a stirred solution ofN,N’-dicyclohexylcarbodiimide (DCC, 170 mg, 0.825 mmol), 1-hydroxybenzotriazole monohydrate (HOBt H2O, 180 mg,1.05 mmol) and 2-[3,4-bis(4-methoxyphenyl)isoxazol-5-yl]aceticacid (mofezolac) (200 mg, 0.59 mmol) in anhydrous CH2Cl2 (20 mL)kept at 0 C. The reaction mixture was stirred for 19h at roomtemperature. Then, H2O was added and the aqueous solutionextracted with CH2Cl2. The combined organic layers were washedwith a sat. aqueous solution of K2CO3, dried over anhydrousNa2SO4, and the solvent was removed under reduced pressure.Column chromatography of the crude residue (silica gel; EtOAc/Hexane 3:7) allowed to isolated 8 (107 mg, 40% yield).
