Reaction Steps

5-Bromopyrimidine (1 g, 6 mmol, 1 eq), 3-aminobenzonitrile (0.892 mg, 7.55 mol, 1.20 eq), Cs2CO3 (2.87 g, 8.81 mmol, 1.40 eq), Pd2(dba)3 (347 mg, 0.603 mmol, 0.080 eq), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (437 mg, 0.755 mmol, 0.120 eq) and dioxane (15 mL) were added to a microwave vial. The vial was purged with argon, capped and heated at 100° C. for 18 h. After cooling the reaction was filtered over a plug of celite and the plug was washed with 5% MeOH/CH2Cl2. The solvents were removed in vacuo and the crude mixture was purified by flash chromatography on silica gel afforded 1.1 g (89%) of the title compound as an orange solid: 1H NMR (400 MHz, CDCl3) δ 8.86 (s, 1H), 8.73 (s, 1H), 8.63 (s, 2H), 7.49-7.43 (m, 2H), 7.43-7.39 (m, 1H), 7.32 (dt, J=7.2, 1.4 Hz, 1H); [M+1]+: 197.2.
