Abstract
The title compound, C20H17F3N 2O4, named tasquinimod, is a second-generation oral quinoline-3-carboxamide analogue, which is currently in phase III clinical trials for the treatment of metastatic prostate cancer. The quinoline unit is almost planar (r.m.s. deviation of fitted atoms = 0.0075 Å). The carboxamide side chain, substituted at position 3, is tilted by 88.07 (7)° to the quinoline plane. Both the methyl and carbonyl groups of this carboxamide side chain are in a syn conformation. The 4-(trifluoromethyl)phenyl plane is inclined at 50.62 (17)° to the plane of the carboxamide side chain, and at 87.14 (4)° to the plane of the quinoline ring system. The 4-hydroxy H atom acts as a double proton donor in an intramolecular hydrogen bond to the 5-position methoxy O atom and in an intermolecular contact to the 2-oxo group, generating a chain along [010] in the crystal structure.
