Paragraph 0274, (2014/02/16)
A compound of Formula (I) or a pharmaceutically acceptable salt thereof: wherein: R1 represents a group selected from: i) phenyl optionally substituted with one or two substituents independently selected from Me, OMe, CF3, F, Cl and NMe2;furanyl, thiophenyl, pyrrolyl, pyridyl, cyclohexyl or naphthyl, each of which is optionally substituted with one or two substituents independently selected from Me, OMe, CF3, F, Cl and NMe2; andiii) benzo[1,3]dioxo5-yl or 2,3-dihydrobenzo[1,4]dioxin-6-yl; R2 represents CF3, C1-4alkyl, or CHF2; when R1 represents optionally substituted furanyl, thiophenyl, pyrrolyl, pyridyl or naphthyl, R3 represents Et; when R1 represents optionally substituted cyclohexyl, R3 represents Et or Me; otherwise R3 represents Et, Me, Br or OMe, compositions containing them, their use in therapy, for example in the treatment of tuberculosis, and methods for the preparation of such compounds, are provided, together with certain novel compounds.
