实验步骤: Tert-butyl 2-(4-bromophenyl)ethylcarbamate (500 mg, 1.67 mmol), imidazole (170 mg, 2.50 mmol), (CuOTf)2.PhH (84 mg, 0.17 mmol), 1,10-Phenanthroline (360 mg, 2.00 mmol), dba (39 mg, 0.17 mmol), and Cs2CO3 (650 mg, 1.99 mmol) were mixed together in a flask and o-xylene (10 mL) was added. Resulting solution was heated to 120° C. and stirred for four days. Reaction mixture was then cooled, poured into water (20 mL) and extracted with EtOAc (3×20 mL). Combined organics were washed with water (1×20 mL) and brine (2×20 mL), dried over sodium sulfate, filtered, and concentrated Crude product was purified by flash chromatography eluting with 25% Hexanes in EtOAC to pure EtOAc to give tert-butyl 2-[4-(1H-imidazol-1-yl)phenyl]ethylcarbamate. Reaction mixture was then cooled extracted with EtOAc (3×20 mL) Combined organics were washed with water (1×20 mL) and brine (2×20 mL) dried over sodium sulfate filtered concentrated Crude product was purified by flash chromatography eluting with 25% Hexanes in EtOAC to pure EtOAc

实验步骤: A mixture of [2-(4-bromo-phenyl)-ethyl]-carbamic acid tert-butyl ester (500 mg), 3-hydroxybenzeneboronic acid (296 mg), sodium carbonate (265 mg), palladium (II) acetate (7 mg) and tricyclohexylphosphine (10 mg) in water (3 ml) and dioxane (12 ml) is kept at 90° C. under micro wave conditions for 180 min. The mixture is cooled down to rt and is filtered through an EXTUBE extraction column (Varian) with EtOAc (200 ml). The filtrate is evaporated and the resulting crude product is purified on silica (150 g) with cyclohexane/EtOAc 5/1 to afford pure [2-(3′-hydroxy-biphenyl-4-yl)-ethyl]-carbamic acid tert-butyl ester. is filtered through an EXTUBE extraction column (Varian) with EtOAc (200 ml) The filtrate is evaporated the resulting crude product is purified on silica (150 g) with cyclohexane/EtOAc 5/1

实验步骤: Compound 113 (530 mg, 1.8 mmol) was dissolved in dry DMF (17 mL) under N2. Zn(CN)2 (416 mg, 3.6 mmol) and Pd(PPh3)4 (200 mg, 0.18 mmol) was added. The reaction mixture was stirred and heated at 150° C. in a microwave instrument (CEM Discover®) for 20 min and the reaction mixture was then concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with EtOAc/hexanes (20˜80%) to yield 114 (540 mg, 31%) as a white solid. MS (APCI, negative): m/z 245 [M−H]+. the reaction mixture was then concentrated in vacuo The residue was purified by flash chromatography on silica gel eluting with EtOAc/hexanes (20˜80%)

实验步骤: tert-Butyl [2-(4-bromophenyl)ethyl]carbamate (0.52 g, 1.73 mmol) was dissolved in dry DMF (17 mL) under nitrogen atmosphere. Zinc cyanide (0.41 g, 3.46 mmol) and tetrakis(triphenylphosphine)palladium (0.16 g, 0.14 mmol) was added. The reaction mixture was heated in a microwave reactor at 150° C. for 20 mins. The procedure was repeated two more times with equal amount of starting material and the resulting three mixtures were combined. The mixture was diluted with EtOAc, washed with saturated aqueous NaHCO3 and water, dried with Na2SO4, filtered and evaporated. The crude product was purified using Biotage Horizon HPFC system (40+M column, isocratic run DCM/MeOH (99.5:0.5, 960 mL), gradient run DCM/MeOH (99.5:0.5-92:8, 240 mL), isocratic run DCM/MeOH (92:8, 720 mL)) affording the title compound (1.14 g, 88.9%). 1H NMR (500 MHz, CDCl3): δ 1.44 (s, 9H), 2.88 (t, 2H), 3.40 (q, 2H), 4.58 (bs, 1H), 7.32 (d, 2H), 7.61 (d, 2H); Mass Spectrum: M+H+ 247. washed with saturated aqueous NaHCO3 and water dried with Na2SO4 filtered evaporated The crude product was purified
