反応手順
The following were introduced into 282 ml of triglyme: 112.8 grams of 2-nitro-5-chloro-trifluoromethylbenzene, 64.1 grams of 5,5-dimethyl-hydantoin and 33.5 grams of cuprous oxide. The mixture was heated to about 215° C.±5° C. for 4 hours, then cooled to 20° C. and filtered. The triglyme solution was recovered and a 22 Be ammonia solution (1V), toluene (1V) and demineralized water (4V) were added to the solution of triglyme (1V). The solution was stirred at 20° C. for 15 minutes, then cooled to about -10° C. and stirred again at -10° C. After washing and drying, 47.6 grams of the desired product were obtained.
