Reaction Steps

(1R)-2-[(6-Chloropyrimidin-4-yl)amino]-1-phenylethanol (75 mg, 0.30 mmol), 2,2-difluoro-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzo[1,3]dioxole (85 mg, 0.30 mmol), Pd(OAc)2 (1.3 mg, 0.006 mmol, 2 mol %), 2-dicyclohexylphosphino-2′,6′-dimethoxy-1,1′-biphenyl (S-Phos) (4.9 mg, 0.012 mmol, 4 mol %) and K3PO4 (191 mg, 0.900 mmol) were dissolved in dioxane (1.0 mL), which had been degassed by bubbling N2 into the solvent and water (0.1 mL) in a sealed tube. The tube was flushed with N2 and heated at 100° C. for 16 h before cooling to rt and filtering through a pad of celite. The celite was washed with CH2Cl2 (5 mL) and the filtrate concentrated to dryness. The crude material was purified by (FCC) to yield the title compound (92 mg, 83%). MS (ESI): mass calcd. for C19H15F2N3O3, 371.11; m/z found, 372.1 [M+H]+. 1H NMR (CDCl3): 8.64 (s, 1H), 7.73-7.71 (m, 2H), 7.43-7.37 (m, 4H), 7.34-7.30 (m, 1H), 7.14-7.12 (m, 1H), 6.65 (d, J=1.1 Hz, 1H), 5.31-5.25 (br hump, 1H), 5.01-4.99 (m, 1H), 3.91-3.85 (br hump, 1H), 3.64-3.59 (m, 1H).
