Procedure

A solution of (R)-tert-butyl 3-(4-amino-6-bromo-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (9) (200 mg, 0.36 mmol) and CuCN (110 mg, 1.08 mmol) in DMF (10 mL) was purged with N2 for three times. The resulting mixture was stirred at 160° C. overnight. After cooling to r.t., the reaction mixture was concentrated to obtain the crude product which was purified by flash chromatography (silica gel, 0 to 100% ethyl acetate in petroleum ether) to afford (R)-tert-butyl 3-(4-amino-6-cyano-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (101) (117 mg, 65% yield) as a yellow solid. LC-MS (ESI): m/z (M+1) 497.1.
