실험 절차

A mixture of N1-(1-(2-fluoroethyl)azetidin-3-yl)-3-methoxybenzene-1,4-diamine (870 mg, 3.64 mmol) and (2-chloro-4-(3-nitrophenoxy)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)methyl pivalate (1.55 g, 3.83 mmol), potassium carbonate (1.35 g, 9.77 mmol), tris(dibenzylideneacetone)dipalladium (173 mg, 0.19 mmol) and dicyclohexyl (2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (222 mg, 0.47 mmol), a magnetite, and t-BuOH (35 mL) was heated to reflux and stirred under nitrogen for 2 h. The mixture was cooled to 40-50° C. and was filtered through diatomaceous earth, washing with ethyl acetate (50 mL). The filtrate was concentrated under reduced pressure. The crude material was purified by column chromatography (DCM/MeOH=50/1 as elution) to give the title compound (1.7 g, yield 74%, M+H+=608.3) as a light yellow solid.
