Versuchsvorschrift

A mixture of 1-(4-amino-3-(methylamino)phenyl)-4-((4-chlorobenzyl)oxy)pyridin-2(1H)-one (200 mg), HATU (224 mg), cis-2-fluoro-cyclopropanecarboxylic acid (100 mg), N,N-diisopropylethylamine (288 μl) and DMF (4 ml) was stirred at room temperature under a dry atmosphere (CaCl2 tube) for 1 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 (4.0 ml) and stirred at 90° C. for 1 h. After AcOH was evaporated, the residue was purified by NH silica gel column chromatography (hexane/EtOAc). The resulting solid was recrystallized from EtOH to give the title compound (37.6 mg) as an off-white solid.
