Prepared as described above for diethyl (4-{[4-chloro-5-(trifluoromethyl)pyrimidin-2-yl]amino}-3-methoxybenzyl)phosphonate using ethyl (4-aminobenzyl)methylphosphinate in place of diethyl (4-amino-3-methoxybenzyl)phosphonate. Following chromatography, the semi-pure product was crystallized from ethyl acetate to afford 1.1 g (61% yield) of the title compound. 1H NMR (400 MHz, DMSO-d6) δ ppm 10.64 (s, 1H), 8.79 (d, J=0.51 Hz, 1H), 7.62 (d, J=8.34 Hz, 2H), 7.25 (dd, J=2.27, 8.59 Hz, 2H), 3.86-4.01 (m, 2H), 3.15 (d, J=17.68 Hz, 2H), 1.31 (d, J=13.64 Hz, 3H), 1.19 (t, J=6.95 Hz, 3H); MS (ES+): m/z: 396.0708 [MH+]. HPLC: tR=1.41 min (UPLC TOF MS: polar—3 min).
