Procedure

To a solution of 3-methoxy-4-[5-(5-methyl-3-phenyl-isoxazol-4-yl)-[1,3,4]oxadiazol-2-yl]-phenylamine (200 mg, 0.57 mmol) in tetrahydrofuran (4 mL) were added N,N-diisopropylamine (111 mg, 0.86 mmol), 4-dimethylaminopyridine (7.0 mg, 0.06 mmol) and acetyl chloride (59 mg, 0.75 mmol) and the reaction mixture was stirred at ambient temperature for 6 h. The resulting suspension was extracted with ethyl acetate (20 mL) and the combined organic layers were washed with aqueous sodium carbonate (saturated). Drying over sodium sulfate and concentration afforded the title compound (162 mg, 72%) as a yellow solid. MS: m/e=391.2 [M+H]+.
