실험 절차

To 3-(6-Bromo-pyridin-3-ylmethyl)-1H-pyrrolo[2,3-b]pyridine (6a, 50.0 mg, 0.000174 mol, prepared as described in Example 2) in 1,4-dioxane (4.0 mL) were added 4-trifluoromethyl-benzamide (51, 70.0 mg, 0.37 mmol), Xanthphos (15.0 mg, 0.026 mmol), cesium carbonate (130.0 mg, 0.40 mmol) and Tris(dibenzylideneacetone)-dipalladium(0) (25.0 mg, 0.024 mmol) under an atmosphere of nitrogen. The reaction was heated to 120° C. for 10 minutes in a CEM Discover microwave instrument. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 50% ethyl acetate in hexane to give a white solid (P-0072, 4.7 mg, 6.8%). MS (ESI) [M+H+]+=397.2.
