실험 절차

A solution of 8.1 g of 5-(3-chloropropyl) 1-(p-cyanophenylmethyl)-1H-imidazole in 50 ml of tetrahydrofuran is cooled to 0°. To this is added 7.0 g of potassium t-butoxide as a solid in portions. The mixture is stirred at room temperature for 2 h, neutralized with 10% acetic acid and partitioned between methylene chloride and water. The organic layer is washed with water, dried over magnesium sulfate and evaporated to yield an oil which is dissolved in a small volume of acetone and neutralized with ethereal hydrogen chloride. On cooling, the title compound is obtained as a white solid, m.p. 201°-203°.
