4-Amino-6-[(3S)-3-(dimethylamino)pyrrolidin-1-yl]-5-(3,3-dimethylbutyn-1-yl)biphenyl-3-carbonitrile (I-246) (54 mg, 0.14 mmol) was dissolved in acetonitrile (3 ml), and at room temperature, bis(acetonitrile)palladium(II) dichloride (7.3 mg, 0.28 mmol) was added, followed by heating under reflux for 3 hours. After cooling to room temperature, the reaction liquid was fractionated with chloroform and an aqueous saturated sodium hydrogencarbonate solution. The organic layer was washed with saturated brine, then dried over anhydrous sodium sulfate. The insoluble matter was separated by filtration, the solvent was evaporated away, and the resulting residue was purified by preparative TLC (eluent, chloroform:methanol=95:5) to obtain a crude product of the entitled compound (32 mg, 60%) as a pale brown gel. This was recrystallized from hexane/diethyl ether to obtain the entitled compound (15 mg) as a pale brown powder.
