This 7-trifluoromethylquinoxalin-2-one was allowed to react with phosphorus oxychloride (in the same manner as described above for 6-trifluoromethylquinoxalin-2-one) to yield the intermediate 2-chloro-7-trifluoromethylquinoxaline having a melting point of about 119°-120° C. This compound was allowed to react with ammonia, in the manner described above, to yield the 2-amino-7-trifluoromethylquinoxaline, having a melting point of about 192°-194° C., and identified by IR spectrum.
