Reaction Steps

To a 8-mL vial was added Pd2(dba)3 (0.028 g, 0.03 mmol), 2-dicyclohexylphosphinobiphenyl (0.025 g, 0.070 mmol), and N4-{4-[(2-chloropyridin-4-yl)oxy]phenyl}&phenylpyrimidine-2,4-diamine (0.20 g, 0.51 mmol, Example 48). The vial was sealed, evacuated, and back filled with nitrogen. THF was then added via syringe, followed by addition of LiHMDS (1M in THF, 0.72 mL, 0.72 mmol). The mixture was heated at 65° C. overnight. The mixture was then cooled to rt, treated with 1N HCl, and stirred for 12 h at rt. The mixture was then neutralized using 1N NaOH and extracted with methylene chloride (10 mL×3). The organic extracts were combined, washed with brine, dried over magnesium sulfate, and purified by preparative HPLC to furnish 0.035 g of the desired product (18%). 1H NMR (CD3OD) δ 7.96 (d, 2H), 7.79 (m, 3H), 7.60 (m, 3H), 7.22 (m, 2H), 6.61 (d, 1H), 6.58 (s, 1H), 6.20 (s, 1H); MS ES 371 (M+H)+ calcd 371.
