实验步骤: To a solution of 4-benzyl-1H-imidazole (example 110C) (1.23 g, 7.78 mmoles) in ACN (20 mL) are added K2CO3 (1.29 g, 9.34 mmoles), Cs2CO3 (253 mg, 0.778 mmole) and methanesulfonic acid phenethyl ester (example 4D) (1.86 g, 9.34 mmole). The reaction mixture is heated at reflux overnight, then cooled to room temperature, filtered, cake washed with ACN and filtrate concentrated under reduced pressure. The residue is purified by silica gel chromatography using (toluene:acetone) (90:10) to give 4-benzyl-1-phenethyl-imidazole. The reaction mixture is heated at reflux overnight filtered cake washed with ACN and filtrate concentrated under reduced pressure The residue is purified by silica gel chromatography

实验步骤: To a solution of 5-methyl-4-phenyl-1H-imidazole (example 103D) (1.02 g, 6.44 mmoles) in ACN (20 mL) are added K2CO3 (1.07 g, 7.72 mmoles) and methanesulfonic acid phenethyl ester (example 4D). The reaction mixture is heated at reflux overnight, then cooled to room temperature, filtered, cake washed with ACN and solvent is removed under reduced pressure. The residue is purified by silica gel chromatography using (toluene:acetone) (90:10) as eluent to give 5-methyl-1-phenethyl-4-phenyl-imidazole and 4-methyl-1-phenethyl-5-phenyl-imidazole. The reaction mixture is heated at reflux overnight filtered cake washed with ACN and solvent is removed under reduced pressure The residue is purified by silica gel chromatography

实验步骤: To a solution of 2-phenylethanol (24.4 g, 0.2 mole) in CH2Cl2 (200 mL) is added NEt3 (30.7 mL, 0.22 mole). The reaction mixture is cooled to 0° C. and methanesulfonyl chloride (16.3 mL, 0.21 mole) is added dropwise. The reaction mixture is allowed to reach room temperature and is stirred at room temperature overnight. Solvent is removed under reduced pressure. Water is added and the aqueous phase is extracted three times with Et2O. The organic phase is washed with water, brine, dried over magnesium sulphate, filtered and the solvent is removed under reduced pressure to give methanesulfonic acid phenethyl ester. to reach room temperature Solvent is removed under reduced pressure Water is added the aqueous phase is extracted three times with Et2O The organic phase is washed with water, brine dried over magnesium sulphate filtered the solvent is removed under reduced pressure

实验步骤: To a solution of 4-phenyl-1H-imidazole (1 g, 8.75 mmoles) in DMF (8 mL) is added NaH 60% dispersion in mineral oil (455 mg, 11 mmoles). The reaction mixture is stirred at room temperature for 1 hour, then methanesulfonic acid phenethyl ester (example 4D) (1.84 g, 9.12 mmoles) is added. The reaction mixture is then heated at 60° C. for 2 hours. Water is added, and the aqueous phase is extracted three times with AcOEt. The organic phase is washed with water, brine, dried over magnesium sulphate, filtered and the solvent is removed under reduced pressure. The residue is purified by silica gel chromatography using (CH2Cl2:MeOH) (100:0) then (98:2) to give 1-phenethyl-4-phenyl-imidazole. The reaction mixture is then heated at 60° C. for 2 hours the aqueous phase is extracted three times with AcOEt The organic phase is washed with water, brine dried over magnesium sulphate filtered the solvent is removed under reduced pressure The residue is purified by silica gel chromatography
