Procedure

A solution of 2-chloro-7-(4-methoxybenzyl)-6-(4-(pyridin-4-yl)phenoxy)-7H-purine (48 mg, 0.11 mmol), 4-aminobenzonitrile (20 mg, 0.17 mmol), Pd(OAc)2 (2 mg, 0.009 mmol), BINAP (9 mg, 0.014 mmol), and Cs2CO3 (43 mg, 0.13 mmol) in toluene (2 mL) was degassed by bubbling nitrogen for 15 min then heated at 80° C. overnight. The desired product was precipitated with EtOAc (10 mL) and saturated NaHCO3. NMR (DMSO-d6): 10.00 (s, 1H), 8.70 (d, 2H), 8.41 (s, 1H), 7.98 (d, 2H), 7.82 (d, 2H), 7.75 (d, 2H), 7.53 (m, 4H), 7.38 (d, 2H), 6.98 (d, 2H), 5.38 (s, 2H), 3.74 (s, 3H); MS (ESI): m/z 526 (M+1)+.
