実験手順

To N,N-dimethylformamide (200 mL) under nitrogen atmosphere add 4-(1H-imidazol-1-yl)benzoic acid (7.0 g, 37 mmol) and 1,1-carbonyldiimidazole (6.0 g, 37 mmol) and stir for 1 h. Add 4-phenyl-1-(phenylmethyl)-2-piperazinemethanamine (9.5 g, 34 mmol) and stir. Monitor the progress of the reaction by thin-layer chromatography. Upon completion of the reaction remove the solvent in vacuo. To the oil add water (100 mL), a saturated solution of sodium bicarbonate (30 mL) andmethylene chloride (200 mL) and stir for 1 h. Separate the layers and extract the aqueous layer with methylene chloride. Concentrate the combined organic layers to give an oil. Flash chromatograph the oil on silica (1000 g) with a mixture of methylene chloride, methanol, triethylamine (97/2/1). Combine and concentrate the fractions containing product. Recrystallize the solid from ethyl acetate/hexane to provide the title compound.
