反応手順
1.3 pts. by wt. of 1-amino-2,3-dioxo-piperazine, 1.3 pts. by wt. of 5-methyl-furfural and 7 pts. by vol. of glacial acetic acid are warmed to 90° C. for 10 minutes and then left for 30 minutes at RT. The precipitate is filtered off, washed first with 3 pts. by vol. of glacial acetic acid and then three times with 10 pts. by vol. of ethyl acetate and dried in air. 1.7 pts. by wt. (76.6%) of 1-(5-methyl-furfurylideneamino)-2,3-dioxo-piperazine of decomp. pt. 245°-8° C. are obtained.
