실험 절차

The suspension of monosodium cyanamide (4.3 g, 67.2 mmol) in absolute ethanol (170 mL) was slowly treated with 4-cyanophenylisothiocyanate (10.75 g, 67.2 mmol). The reaction was allowed to stir at room temperature for 1 hour and then heated at 75° C. for 4 hours. The reaction was cooled to room temperature and the colorless solid was filtered and washed with ethanol to give the title A compound (10.0 g), m.p. >250° C.
