实验步骤: A 2 mL Biotage™ microwave vial was charged with copper iodide (1.1 mg, 10 mol %), and Pd(PPh3)2Cl2 (2.1 mg, 5 mol %). A solution of (6-chloro-5-iodo-1H-benzoimidazol-2-ylsulfanyl)-acetic acid tert-butyl ester (Intermediate 4, 25.0 mg, 0.059 mmol) in DMF (0.5 mL) was added to the vial, followed by a solution of (4-ethynyl-phenyl)-methanol (15.0 mg, 0.118 mmol) in DMF (250 uL) and TEA (57 uL, 0.41 mmol). The resulting suspension was heated in a microwave synthesizer (Biotage Initiator™) at 120° C. for 5 min. The solvent was removed in vacuo to give dark brown oil which was used in the next step without further purification. LR-MS (API-ES): calculated for C22H21ClN2O3S 428.1, observed m/e 429.0 (M+H)+ (Rt 3.05 min). The solvent was removed in vacuo to give dark brown oil which was used in the next step without further purification

实验步骤: (4-Ethynylphenyl)methanol (200 mg, 1.51 mmol) and diisopropylamine (360 mg, 3.56 mmol) were added to a solution of methyl (Z)-[4-[3-(4-bromophenyl)-3-(4-iodophenyl)allyloxy]-2-methylphenoxy]acetate (445 mg, 0.75 mmol) in anhydrous tetrahydrofuran (15 mL). The solution was degassed and bis(triphenylphosphine)palladium(II) dichloride (30 mg, 0.042 mmol) and copper(I) iodide (15 mg, 0.078 mmol) were added. The reaction solution was degassed again and then stirred under inert atmosphere at ambient temperature over night. The reaction mixture was filtered through a paddle of silica gel; the paddle was thoroughly washed with ethyl acetate (4×20 mL) and the combined filtrates were concentrated in vacuo. The residue was purified by column chromatography (silica gel Fluka 60, dichloromethane/methanol 98:2) yielding methyl (E)-[4-[3-(4-bromophenyl)-3-[4-[4-(hydroxymethyl)phenylethynyl]phenyl]allyloxy]-2-methylphenoxy]acetate.

实验步骤: 1,5-bis-benzyloxy-2-isopropyl-4-azido-benzene (890 mg, 2.38 mmol) was dissolved in DMF (5 ml) and (4-ethynylphenyl)-methanol (286 mg, 2.16 mmol) was added at RT. The flask was subjected to three vacuum-nitrogen cycles. [Cp*RuCl]4 was then added (116 mg, 0.11 mmol) and three further cycles were done. The reaction was left to RT until completion (monitored by TLC). AcOEt and water were then added. The organic phase was extracted four times with AcOEt, washed with water (three times) and brine (one time) and dried over Na2SO4; the solvent was removed under reduced pressure and the mixture was purified by column chromatography (PE/AcOEt: 60:40). The title compound was obtained as an oil.
