Bodnarchuk, N. D. published the artcileSubstituted 1,1-diaminoethylenes, Name: Ethyl 5-amino-3-methyl-1H-pyrazole-4-carboxylate, the publication is Zhurnal Organicheskoi Khimii (1973), 9(1), 36-8, database is CAplus.

Six RO2CCX:C(NH2)CY3 (I; R = Me, Et, Me2CH, Me3C; X = MeO2C, EtO2C, Me3CO2C, CN; Y = Cl, F) reacted with R1NH2 [R1 = Pr, Bu, C6H13, HOCH2CH2, Me2CHCH2, NH2, Et2NCH2CH(OH)CH2] to give 18 corresponding RO2CCX:C(NH2)NHR1 in 71-95% yield; I (Y = F) required higher reaction temperatures than I (Y = Cl). EtO2CC(COMe):C(NH2)CF3 and N2H4.H2O in DMF yielded 95% pyrazole II (R2 = Me); EtO2CC(CN):C(NH2)NHNH2 was cyclized to 98 % II (R2 = NH2) in refluxing PhOEt.
