Procedure

To a solution of the compound [122](29.7 mg) in N,N-dimethylformamide (0.8 mL) were added zinc cyanide (4.8 mg), tris(dibenzylideneacetone)dipalladium(0) (3.7 mg) and 2-dicyclohexylphosphino-2,4,6-triisopropylbiphenyl (7.8 mg) at room temperature, and then the reaction mixture was subjected to microwave irradiation at 160° C. for 30 minutes. The reaction mixture was quenched with water, and extracted with ethyl acetate, and then the obtained organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by reverse phase preparative liquid chromatography to give the titled compound (13.3 mg) as a white solid.
