The title compound was prepared according to the procedure from Example 102 using diethyl (4-{[4-chloro-5-(trifluoromethyl)pyrimidin-2-yl]amino}benzyl)phosphonate (179.0 mg, 0.4224 mmol) and 7-amino-2,3-dimethyl-2,3-dihydro-1H-isoindol-1-one (Compound 157A, 83.7 mg, 0.475 mmol). The reaction mixture was poured into a separatory funnel containing saturated NaHCO3 and was extracted with EtOAc. The combined organic layers were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. The crude was purified using a Teledyne/ISCO Combiflash system, eluting first with 40-100% EtOAc:Heptane and then 0-15% MeOH:CH2Cl2. The product was purified again by MDP (under basic conditions; ammonium bicarbonate buffer (pH 9)) to afford the title product as an off-white solid (158.3 mg, 65%). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.61 (br s, 1H), 9.93 (s, 1H), 8.71 (br s, 1H), 8.48 (s, 1H), 7.38-7.80 (m, 3H), 7.15-7.33 (m, 3H), 4.59 (q, J=6.6 Hz, 1H), 3.90-4.02 (m, 4H), 3.22 (d, J=21.5 Hz, 2H), 3.01 (s, 3H), 1.43 (d, J=6.6 Hz, 3H), 1.18 (t, J=6.9 Hz, 6H). MS (ES+): m/z 564.17 (100) [MH+]. HPLC: tR=1.56 min (TOF, polar—3 min).
