Reaction Steps

To a solution of ethyl 3-bromo-1-(3-methoxypropyl)-1H-pyrrolo[3,2-c]pyridine-6-carboxylate (200 mg) in 1,4-dioxane (2 mL) were added trivinylboroxine pyridine complex (141 mg), cesium carbonate (573 mg), 2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl (X-Phos) (56 mg) and tris(dibenzylideneacetone)dipalladium (27 mg) under argon, and the mixture was stirred at 100° C. for 1 hour. The reaction solution was cooled, and then thereto was washed with saturated saline, dried over sodium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=9/1→4/1) to give ethyl 1-(3-methoxypropyl)-3-vinyl-1H-pyrrolo[3,2-c]pyridine-6-carboxylate [REx(106-1)] (118 mg) as a yellow oil.
