Reaction Steps

To a solution of 6-chloro-4-(1-phenylcyclopropylamino)nicotinamide (50 mg, 0.174 mmol) in dioxane (1 mL) was added 1-(4-(4-aminophenyl)piperazin-1-yl)propan-1-one (61 mg, 0.261 mmol), BINAP (22 mg, 0.035 mmol), Pd(OAc)2 (8 mg, 0.035 mmol) and Cs2CO3 (170 mg, 0.52 mmol). After degassed with Argon, the mixture was heated at 80° C. for 15 h. The mixture was diluted with dioxane, precipitate was filtered off, filter cake was washed with AcCN, the filtrate was concentrated and purified by preparative HPLC to give of 4-(1-phenylcyclopropylamino)-6-(4-(4-propionylpiperazin-1-yl)phenylamino)nicotinamide (16 mg). MS found for C28H32N6O2 as (M+H)+ 485.5. λ=258.2.
