Diisopropylethylamine → N-(4-(6-(4-(Benzyloxy)phenylamino)pyrimidin-4-yloxy)-3-fluorophenyl)-N3-(4-fluorophenyl)malonamide

Participants

Reaction Steps

The title compound was prepared from a mixture 6-(4-amino-2-fluorophenoxy)-N-(4-(benzyloxy)phenyl)pyrimidin-4-amine (45 mg, 0.11 mmol), 3-(4-fluorophenylamino)-3-oxopropanoic acid (Compound B of Example 1, 24 mg, 0.12 mmol), TBTU (48 mg, 0.15 mmol), DIPEA (0.26 mL, 0.15 mmol), and DMF (1 mL) using a similar procedure described for the preparation of Compound C of Example 1. The crude product was triturated with isopropyl ether to give the title compound (56 mg, 88%) as a pink solid. 1H NMR (DMSO-d6) δ 10.47 (s, 1H), 10.27 (s, 1H), 9.45 (s, 1H), 8.25 (s, 1H), 7.77 (dd, 1H, J=12.7, 2.0 Hz), 7.65-7.62 (m, 2H), 7.46 (d, 4H, J=7.3 Hz), 7.40 (dd, 2H, J=7.6, 7.3 Hz), 7.37-7.29 (m, 3H), 7.17 (dd, 2H, J=9.0, 8.3 Hz), 7.00 (d, 2H, J=9.0 Hz) 6.09 (s, 1H), 5.09 (s, 2H) 3.49 (s, 2H); MS(ESI+) m/z 582.3 (M+H)+.
