Page/Page column 224-225, (2018/04/20)
The present invention relates to compounds of formula (I), and salts and solvates thereof, that function as inhibitors of cell division cycle 7 (Cdc7) kinase enzyme activity: (Formula (I)) wherein X, R1, R2, and n are each as defined herein. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of proliferative disorders, such as cancer, as well as other diseases or conditions in which Cdc7 kinase activity is implicated.

2-Amino-4,6-dichloro-5-nitropyrimidine is an intermediate required for the preparation of nitropyrimidines as inactivators of the DNA repairing protein MGMT. When attempting its synthesis, 2-amino-4,5,6-trichloropyrimidine is obtained instead, via unusual aromatic substitution of the nitro group in 2-amino-4-hydroxy-5-nitropyrimidin-6-one by chloride. The synthesis, the reactivity of 4,5,6-trichloropyrimidine and the efficient preparation of 2-amino-4,6-dichloro-5-nitropyrimidine are presented.
