Reaction Steps

To a solution containing 2-propen-1-yl {3-[5-(2-chloro-4-pyrimidinyl)-2-(1-methylethyl)-1,3-thiazol-4-yl]phenyl}carbamate (5.3 g, 12.77 mmol) and DCM (225 mL) was added tri-n-butyltin hydride (5.95 g, 20.43 mmol), followed by trans-dichlorobis(triphenylphosphine)palladium (II) (0.53 g, 0.64 mmol) and HOAc (1.84 g, 30.65 mmol). At the conclusion of the reaction, silica was added and the volatiles removed under reduced pressure. The residue was purified by flash column chromatography with (84% DCM, 15% MeOH, and 1% NH4OH): DCM 0% to 100% to afford 3.4 g of the title compound. 1H-NMR (400 MHz, DMSO-d6) δ 8.57 (d, J=5.1 Hz, 1H), 7.16 (d, J=5.1 Hz, 1H), 7.10 (t, J=7.7 Hz, 1H), 6.72-6.75 (m, 1H), 6.64-6.69 (m, 1H), 6.60-6.63 (m, 1H), 5.28 (s, 2H), 3.27-3.40 (m, 1H), and 1.38 (d, J=7.0 Hz, 6H). MS (ESI): 331 [M+H]+.
