実験手順

A mixture of 1-(4-amino-3-(methylamino)phenyl)-4-((4-chlorobenzyl)oxy)pyridin-2(1H)-one (90 mg), HATU (101 mg), N,N-diisopropylethylamine (0.130 ml), cyclobutanecarboxylic acid (0.024 ml) and DMF (2 ml) was stirred at room temperature for 2 h. The mixture was quenched with water and extracted with EtOAc. The organic layer was separated, washed with water and brine, dried over MgSO4 and concentrated in vacuo. The residue was dissolved in AcOH (2 ml), and the mixture was stirred at 90° C. for 1 h. After evaporation, the residue was purified by NH silica gel column chromatography (hexane/EtOAc). The resulting solid was recrystallized from EtOH to give the title compound (22.72 mg) as an off-white solid.
