Paragraph 0035-0037, (2018/03/23)
The invention discloses a synthesis method of 2-amino-4-fluoropyridine. The synthesis method comprises the following synthesis steps: 1, taking diaminopyridine as the raw material, carrying out oxidation reaction to prepare 2-aminopyridine N-oxide a; 2, subjecting the compound a to nitration reaction with mixed acid to obtain 2-amino-4-nitropyridine N-oxide b; 3, carrying out acylation reaction onthe compound b and an acylation reagent to obtain 2-acetamino-4-nitropyridine N-oxide c; 4, carrying out reduction reaction on the compound c to obtain 2-acetamino-4-aminopyridine d; 5, carrying outdiazo-reaction on the compound d and HBF4 to obtain diazonium fluoroborate e; and 6, carrying out Balz-Schiemann reaction on the compound e to introduce fluorine atoms and conducting hydrolysis deacetylation to obtain 2-amino 4-fluoropyridine. The method provided by the invention solves the problems of long synthesis route, complicated operation, serious pollution, high cost, low yield and the like in existing synthesis methods.

The importance of complete elucidation of the biological functions of phosphoinositide 3-kinases (PI3K) was realized years ago. They generate 3-phosphoinositides, which are known to function as important second messengers in many inter- and intracellular signaling pathways. However, the functional role of class II PI3Ks is still unclear. Herein, we describe the synthesis of a panel of compounds that were tested against all eight mammalian PI3K-isoforms. We found inhibitors with some selectivity for class II PI3K-C2γ and also compounds with preferred inhibition of class II PI3K-C2β, providing structural leads to develop selective tool compounds.
