Reaction Steps

To a solution of 4-hydroxy-2,2-dimethyl-2,3-dihydro-benzofuran-6-carboxylic acid (1-methyl-1H-pyrazol-3-yl)-amide (31a) (80 mg, 0.280 mmol) and 6-(chloromethyl)-2-(pyrazin-2-yl)pyrimidin-4-ol (124 mg, 0.557 mmol) in 3 mL of DMF was added Cs2CO3 (181 mg, 0.557 mmol). The mixture was heated at 60° C. overnight, then filtered, washed with EtOAc, concentrated, and purified by reverse phase HPLC to give a white solid (13 mg, 10% yield). 1H NMR (400 MHz, CDCl3) δ 9.67 (d, J=1.52 Hz, 1 H) 8.83 (d, J=2.53 Hz, 1 H) 8.65-8.67 (m, 1 H) 8.50 (s, 1 H) 7.27-7.31 (m, 1 H) 7.06 (d, J=1.01 Hz, 1 H) 6.88 (s, 1 H) 6.76-6.82 (m, 1 H) 6.72 (s, 1 H) 5.13 (s, 2 H) 3.81 (s, 3 H) 3.11 (s, 2 H) 1.49-1.55 (m, 6 H); LCMS for C24H23N7O4 m/z 474.00 (M+H+).
