Procedure

To a solution of (R)-benzyl 1-(1-(6-chloro-5-cyano-3-fluoropyridin-2-ylamino)propyl)cyclopropylcarbamate (100 mg, 0.25 mmol) in dioxane (1.5 mL) was added p-toluidine (32 mg, 0.30 mmol), BINAP (31 mg, 0.05 mmol), Pd(OAc)2 (11.2 mg, 0.05 mmol) and Cs2CO3 (244.5 mg, 0.75 mmol). After degassed with Argon, the mixture was heated at 80° C. for 5 h. The mixture was diluted with dioxane, precipitate was filtered off, filter cake was washed with ACN, the filtrate was concentrated and purified by column to give of (R)-benzyl 1-(1-(5-cyano-3-fluoro-6-(p-tolylamino)pyridin-2-ylamino)propyl)cyclopropylcarbamate (80 mg).
