実験手順

To a solution of compound 71 (40 mg) in DCM was added DIEA (45 uL) followed by isobutylchloroformate (26 uL). After stirring at room temperature for 30 min, leucine amide (18 mg) and DIEA (25 uL) was added and stirred for 1 h. The reaction mixture was evaporated and dissolved in MeOH, and purified with a preparative LC-MS to give compound 72. LCMS (+ESI) m/z=537.3 [M+H]+.
