실험 절차

A solution of 3.7 g. of cuprous cyanide and 2.6 g. of finely powdered sodium cyanide in 20 ml. of dimethyl sulfoxide is treated dropwise with a solution of 4.12 g. (0.01 mole) of the diazonium tetrafluoroborate salt of 6-(aminophenylthio)-2-(methoxycarbonylamino) imidazo [1,2-a] pyridine obtained in Example 15 in 10 ml. of dimethyl sulfinate. An exotherm is observed and external cooling is necessary. The reaction mixture is stirred at room temperature for one hour, diluted with water and the solids collected by filtration. The solids are washed with water, dried and recrystallized from dimethylformamide-ethanol (50/50) to yield 6-(p-cyanophenylthio)-2-(methoxycarbonylamino) imidazo [1,2-a] pyridine.
