Abstract
The molecular structure of the title compound, C17H15FN2O, was determined in the course of our studies on mitogenactivated protein kinase inhibitors. The exocyclic bond angles at the carbon atoms of the isoxazole ring bearing the pyridyl and 4-fluorophenyl rings are 130.0 (2) and 129.2 (2)degrees, respectively. The pyridine and 4-fluorophenyl rings are twisted relative to the isoxazole ring by 80.2 (2) and 19.1 (1)degrees, respectively.
