Reaction Steps

A suspension of tert-butyl 4-((4-chloro-5-(trifluoromethyl)pyrimidin-2-yl)amino)benzyl(2-hydroxyethyl)carbamate (A71) (0.518 g, 1.15 mmol), Et3N (0.75 mL), methyl 2-(2-ethynylphenyl)acetate (K1) (0.242 g, 1.39 mmol), PdCl2(PPh3)2 (0.041 g, 0.058 mmol), CuI (0.022 g, 0.116 mmol) and PPh3 (0.030 g, 0.12 mmol) in DMF (4.5 mL) was heated under microwave irradiation at 120° C. for 15 minutes. The volatiles were evaporated in vacuo and the residue purified using silica gel column chromatography (CombiFlash Rf, 40 g SiO2 cartridge, 20-50% EtOAc in cyclohexane) to give the title compound A72 as an orange foam (0.589 g, 86%); 1H NMR (300 MHz, CDCl3) δ 8.65 (s, 1H), 7.70 (d, J=7.0 Hz, 1H), 7.63 (d, J=8.3 Hz, 2H), 7.48-7.28 (m, 6H), 4.49 (brs, 2H), 3.97 (s, 2H), 3.72 (m, 5H), 3.47 (brs, 2H), 3.01 (brs, 1H), 1.51 (s, 9H). LCMS-B: rt 8.350 min; m/z 585 [M+H]+.
