Versuchsvorschrift

A solution of ethyl (4-{[4-{[6-bromo-2-(methylcarbamoyl)pyridin-3-yl]amino}-5-(trifluoromethyl)pyrimidin-2-yl]amino}-3-methoxybenzyl)ethylphosphinate (Compound 67C, 1.11 g, 1.76 mmol) in pyridine (15.0 mL) was cooled to 0° C. and then charged with bromotrimethylsilane (1.39 mL, 10.6 mmol). The reaction mixture was slowly warmed to rt with stirring for 72 hours. The reaction mixture was quenched with MeOH (2.3 mL, 57 mmol) and then concentrated under reduced pressure to a yellow oil. The material was dissolved in DCM (10 mL) and washed with 3N HCl (10 mL), was washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated under reduced pressure to a light yellow solid. The acid layer was saturated with solid NaCl and extracted with DCM (10 mL). The organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure to a light yellow solid. Both batches of solid were combined (932.5 mg, 88%). 1H NMR (CDCl3, 400 MHz): δ=8.91 (d, J=8.3 Hz, 1H), 8.34 (s, 1H), 8.10 (q, J=4.6 Hz, 1H), 7.47 (d, J=8.8 Hz, 1H), 6.89 (s, 1H), 6.82 (d, J=8.1 Hz, 1H), 3.87 (s, 3H), 3.00-3.10 (m, 5H), 1.54-1.68 (m, 2H), 1.13 (td, J=7.5, 18.3 Hz, 3H). MS (ESI): m/z 603.42/605.40 [M+H]+. UPLC: tR=1.24 min (UPLC-SQD: analytical—2 min).
