PROCEDURE
实验过程
A screw-cap tube is charged with 2-[(3-bromophenyl)(1-methylpiperidin-4-yloxy)methyl]-1H-benzimidazole (200 mg), palladium bis(dibenzylideneacetone) (14 mg), Xantphos (14 mg), benzyl mercaptan (59 μL), Diisopropylethylamine (174 μL) and 1,4-dioxane (2 mL). The tube is evacuated, filled with argon and sealed. After stirring at 120° C. for 24 h, the mixture is diluted with ethyl acetate and water and the aqueous phase is extracted with ethyl acetate. The pooled organic extracts are dried over magnesium sulfate and concentrated under reduced pressure. The residue is purified by chromatography (gradient dichloromethane/methanol/ammonia from 100/0/0 to 95/5/0.5) to afford 2-[(3-benzylsulfanylphenyl)(1-methylpiperidin-4-yloxy)methyl]-1H-benzimidazole
