Under N2, a mixture of (R)—N-methyl-1-(7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)pyrrolidin-3-amine (50 mg, 0.14 mmol), 3-bromobenzonitrile (39 mg, 0.21 mmol), Pd2(dba)3 (1 mg, 0.002 mmol), BINAP (5 mg, 0.008 mmol) and t-BuONa (27 mg, 0.28 mmol) in toluene (2 mL) was stirred at reflux for 6 hour, cooled to ambient temperature, diluted with EtOAc (50 mL), washed with brine (3×10 mL), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by preparative TLC (DCM:MeOH=20:1) to give the title compound. MS (m/z): 449 (M+H)+.
