A solution of (R)-tert-butyl 1-(7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)pyrrolidin-3-ylcarbamate (700 mg, 1.61 mmol) in HCl (in MeOH, 6 N, 5 mL) was stirred at ambient temperature for 3 hours. The volatiles were removed under reduced pressure. The residue was dissolved in DMSO (3 mL). 6-chloronicotinonitrile (323 mg, 2.41 mmol), KI (10 mg, 0.06 mmol) and DIPEA (311 mg, 2.41 mmol) were then added. The reaction mixture was stirred at 120° C. for 14 h, cooled to ambient temperature, diluted with H2O (20 mL), and extracted with EtOAc (3×40 mL). The combined extracts were washed with brine (3×10 mL), dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by chromatography to give the title compound. MS (m/z): 436 (M+H)+.
