실험 절차

To (4-cyano-3-fluorophenyl)boronic acid (190 mg, 1.15 mmol) and 6-chloro-N4-(phenylmethyl)-2,4-pyrimidinediamine (300 mg, 1.28 mmol) into a sealable flask were added 1,4-dioxane (6 mL) and saturated aqueous NaHCO3 (3 mL). The mixture was degassed with nitrogen gas for 10 minutes. Pd(Ph3P)4 (74 mg, 0.064 mmol) was added and the reaction mixture was stirred overnight at 100° C. The mixture was poured onto EtOAc and water. The organic layer was separated and the aqueous layer was further extracted with EtOAc. The combined organic layers were filtered, then washed with brine, dried (MgSO4), filtered and concentrated. The resulting residue was chromatographed on SiO2 (gradient: 99:1:0.1 CHCl3/CH3OH/NH4OH to 90:10:1 CHCl3/CH3OH/NH4OH). The material (367 mg) was carried on as is into the next reaction.
