실험 절차
A mixture of 628 mg of dimethyl aminoterephthalate, 546 mg of 3-chlorophenylacetonitrile and 15 mL of 4N hydrogen chloride dioxane solution was stirred at room temperature for 7 hours. Further continuing the stirring at 30° C. for 63 hours and at 70° C. for 25 hours, ice was added to the reaction mixture, followed by addition of 7 mL of 25% aqueous ammonia. Whereupon precipitated crystals were recovered by filtration, and washed with water, ether and chloroform by the order stated. Subjecting the crystals to through-flow drying under heating, 670 mg of the title compound was obtained.
