To a solution of 2-acetylamino-5-aminopyridine (150 mg, 0.99 mmol) in pyridine (1.5 ml), 213 mg (1.49 mmol) of 1,2,2-trimethylpropyl isothiocyanate was added dropwise, followed by stirring at room temperature for 22 hours, at 50° C. for 5 hours and further at room temperature for 15 hours. Then, the solvent was removed by distillation under reduced pressure. The residue was recrystallized from chloroform-hexane to obtain 232 g of the intended product as a flesh-colored powder (yield: 79%).
