実験手順

A glass microwave reaction vessel was charged with 4-chloro-6-(4-methoxybenzyloxy)-2-(methylsulfonyl)pyrimidine (600 mg, 1.825 mmol) and tert-butyl 5-bromo-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-1-carboxylate (770 mg, 1.825 mmol) in p-dioxane/H2O (4:1, 6 mL) followed by Pd(PPh3)4 (105 mg, 0.091 mmol) and potassium carbonate (220 μL, 3.65 mmol). The reaction was stirred and heated in a Initiator microwave reactor (Personal Chemistry, Biotage AB, Inc., Upssala, Sweden) at 100° C. for 30 min. The mixture was diluted with water and extracted with DCM. The combined organic layers were dried, filtered and concentrated. The residue was purified with silica gel chromatography (eluting with 10-25% EtOAc in Hexanes) to give tert-butyl 5-bromo-3-(6-(4-methoxybenzyloxy)-2-(methylsulfonyl)pyrimidin-4-yl)-1H-indole-1-carboxylate (445 mg, 0.756 mmol, 41.4% yield) as a half solid. MS (ESI, pos. ion) m/z: 587.8 (M+1).
