Procedure
To a stirring solution of diethyl (4-{[4-{[7-(trans-4-hydroxycyclohexyl)-2-methyl-3-oxo-2,3-dihydro-1H-isoindol-4-yl]amino}-5-(trifluoromethyl)pyrimidin-2-yl]amino}-3-methoxybenzyl)phosphonate (0.45 g, 0.66 m mol) in DCM (1.68 mL), cooled to 0° C., was slowly added triethylamine (0.185 mL, 1.33 mol) followed by methanesulfonyl chloride (0.13 mL, 1.66 mmol) and 4-dimethylaminopyridine (0.81 mg, 6.60 μmol). The mixture was stirred at rt overnight. After 16 hrs, a precipitate formed. The organic layer was re-dissolved in DCM and washed with water (2×), dried over sodium sulfated, filtered and concentrated in vacuo to a solid. The crude product was purified by CombiFlash®Rf 4X Organic Purification System [dried loaded, 3×12 g RediSep® Normal-phase GOLD Silica Flash Column, elution gradient: 0→4% 7N NH3 (MeOH) in DCM] to afford 220 mg (44%) of the desired product. 1H NMR (400 MHz, MeOD) δ 8.48 (br. s., 1H), 8.33 (s, 1H), 7.82 (d, J=8.08 Hz, 1H), 7.40 (d, J=8.59 Hz, 1H), 7.06 (d, J=2.02 Hz, 1H), 6.96 (d, J=7.58 Hz, 1H), 4.74-4.80 (m, 1H), 4.51 (s, 2H), 4.09 (quin, J=7.20 Hz, 4H), 3.89 (s, 3H), 3.34 (s, 1H), 3.29 (br. s., 2H), 3.18 (s, 3H), 3.10 (s, 3H), 2.64 (br. s., 1H), 2.29 (d, J=11.37 Hz, 2H), 1.69-2.00 (m, 6H), 1.28 (t, J=7.07 Hz, 6H). MS (ES+): m/z 756.19/757.23 (100/90) [MH+]. HPLC: tR=1.53 min (Micromass TOF: polar—3 min).
