Participants

Reaction Steps

2-(2-(2-(2-((3-(4-Methylpiperazin-1-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)acetic acid (I68) (75.0 mg, 169 μmol) was dissolved in DMF (1 mL) then HATU (129 mg, 339 μmol), DIPEA (57 μL, 339 μmol) and methylamine (8.0 M in ethanol; 200 μL) were added. The resulting mixture was stirred at room temperature overnight then the volatiles were evaporated under reduced pressure. The residue was diluted with ethyl acetate and washed with 10% NaHCO3, the layers were separated and the organic layer was dried (MgSO4) then evaporated under reduced pressure to give a cream solid. The cream solid was adsorbed onto silica and chromatographed on silica gel (0-10% MeOH/DCM) to give the title compound (18) (9.0 mg, 10%) as a solid; 1H NMR (400 MHz, CD3CN) δ 8.56 (d, J=0.6 Hz, 1H), 8.36-8.28 (m, 1H), 7.39 (s, 1H), 7.20 (ddd, J=5.6, 4.4, 1.9 Hz, 6H), 6.71-6.65 (m, 1H), 6.33-6.23 (m, 1H), 3.56 (s, 2H), 3.22-3.15 (m, 4H), 3.10 (s, 2H), 3.07 (s, 2H), 2.60 (d, J=4.7 Hz, 3H), 2.49-2.43 (m, 4H). LCMS Method C: rt 4.86 min; m/z 513.3.
