Reaction Steps

To a solution of 3-(2-(2-((3-(4-methylpiperazin-1-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)benzoic acid (I30) (0.048 g, 0.10 mmol) and HATU (0.051 g, 0.13 mmol) in DMF (2 mL) was added DIPEA (0.068 mL, 0.39 mmol), the resulting solution was then stirred for 10 minutes before addition of NH4OH (0.2 mL). The resulting mixture was then stirred overnight (16 hours) at room temperature. The mixture was diluted with water and extracted with EtOAc (2×20 mL). The combined organic extracts were dried using a phase separation cartridge before concentrating under reduced pressure. The organic residues were then purified using silica gel column chromatography (0-30% MeOH/EtOAc with 1% NH4OH in the MeOH) to give the title compound (6)(0.028 mg, 58%) as a white solid; NMR (400 MHz, d6-DMSO) δ 10.07 (s, 1H), 8.67 (s, 1H), 7.95 (s, 1H), 7.78 (s, 1H), 7.72 (m, 1H), 7.54 (s, 1H), 7.38 (m, 2H), 7.34 (m, 1H), 7.14 (d, J=5.2 Hz, 2H), 6.64 (m, 1H), 3.10 (m, 8H), 2.42 (m, 4H), 2.19 (s, 3H). LCMS Method C: rt 4.80 min; m/z 485.3 [M+H]+.
