실험 절차

A mixture of 3-bromo-1-cyclopentyl-4-methoxy-4,5-dihydro-1H-pyrrolo[3,2-c]pyridine-7-carbonitrile (400 mg), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene-2-carboxamide (553 mg) obtained in Step B of Example 33, (1,1′-bis(diphenylphosphino)ferrocene)dichloropalladium(II) (102 mg), 2M aqueous sodium carbonate solution (1.24 mL) and DME (3.5 mL) was stirred under microwave irradiation at 120° C. for 1 hr 30 min. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (310 mg).
