실험 절차

The product of Example 1B (trifluoro-methanesulfonic acid 4′-cyano-biphenyl-4-yl ester) (135 mg, 0.55 mmole), the product of Example 1C (198 mg, 0.61 mmole), palladium acetate (2.7 mg, 0.012 mmole), racemic-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP, 20 mg, 0.033 mmole) and sodium tert-butoxide (80 mg, 0.83 mmole) were mixed in 1.5 ml of toluene and heated at 80° C. under N2 for 16 hours. The mixture was cooled to room temperature, diluted with water and extracted with dichloromethane (3×). The combined organics were dried over sodium sulfate and concentrated to provide the crude product, which was purified by chromatography (5% methanol in dichloromethane) to provide the title compound. MS: (M+H)+=424.
