[CH3:1][C:2]1[CH:7]=[CH:6][N:5]=[C:4]([C:8]#[N:9])[N:3]=1.O.[NH2:11][NH2:12]>C(O)C>[CH3:1][C:2]1[CH:7]=[CH:6][N:5]=[C:4]([C:8](=[NH:9])[NH:11][NH2:12])[N:3]=14-methyl-2-pyrimidinecarbonitrile (I98)(0.190 g, 1.595 mmol) was dissolved in ethanol (3.19 ml) and hydrazine hydrate (0.100 ml, 3.19 mmol) was added. The reaction mixture was left at reflux for 2.5 hours. TLC showed that no starting material remained so the solvent was removed under reduced pressure to afford the crude desired product in 247 mg.
