Reaction Steps

Racemic Compound 45A was prepared analogously to Compound 44A using ethyl hydrogen (4-{[4-{[6-bromo-2-(ethylcarbamoyl)pyridin-3-yl]amino}-5-(trifluoromethyl)pyrimidin-2-yl]amino}-3-methoxybenzyl)phosphonate (Compound 45B, 78.1 mg, 0.123 mmol) to afford 37.7 mg of the title compound (34%). MS (ESI): m/z=909.40/991.51 [M+H]+. UPLC: tR=1.60 min (UPLC-TOF: polar—2 min).
