A fluorinated aminopyridine building block

For the synthesis of APIs and metal complexes


2-Amino-5-chloro-3-fluoropyridine (CAS number 246847-98-3) is a pyridine derivative substituted with an amine, a fluorine and a chlorine at the 2-, 3- and 5-positions respectively. The pyridinium amine of 2-amino-5-chloro-3-fluoropyridine can easily coordinate to copper centres, in neutral or acidic media. The resulting organometallic complexes exhibit antiferromagnetic interactions under temperatures ranging from −0.9 to −31.3 K.

2-Amino-5-chloro-3-fluoropyridine is also used in the synthesis of active pharmaceutical ingredients (APIs). These APIs include inhibitors of cyclin-de-pendent kinase for cancer treatments and disruptors of glucokinase-glucokinase regulatory protein for type II diabetes mellitus.
