One aspect of the invention relates to a compound of formula (I), or a pharmaceutically acceptable salt or solvate thereof, (I) wherein: ring A is a 5 or 6 membered aromatic or heteroaromatic ring, wherein said aromatic or heteroaromatic ring is optionally substituted with one or more substituents selected from F, Cl, Br, I, CN, alkoxy, NR11R11',OH, alkyl, haloalkyl, aralkyl, aryl, and heteroaryl, and wherein said aryl and heteroaryl substituents are in turn optionally substituted with one or more substituents each independently selected from F, Cl, Br, I, CN, alkoxy, NR11R11' OH, alkyl, haloalkyl, and aralkyl; Y is selected from C=N-OH and CR10R10' wherein R10 and R10' are each independently selected from H, F, alkyl, and haloalkyl; R1, R4, and R5 are each independently selected from H, F, Cl, Br, and I; R2 and R3 are each independently selected from H, F, Cl, Br, I, CN, methoxy, and haloalkyl; and R11 and R11' are each independently selected from H, alkyl, haloalkyl, COR12, and SO2R13, wherein R12 and R13 are both alkyl; for use as a medicament. Further aspects of the invention relate to compounds of formula (I) for use in the field of immuno-oncology, immunology, and related applications, and compounds of formula (I) per se.
Removal of fluorine from and introduction of fluorine into polyhalopyridines: An exercise in nucleophilic hetarenic substitution

, p. 1903 - 1910 (2007/10/03)
Starting from six industrially available fluorinated pyridines, an expedient access to all three tetrafluoropyridines (2-4), all six trifluoropyridines (5-10), and the five non-commercial difluoropyridines (11-14 and 16) was developed. The methods employed for the selective removal of fluorine from polyfluoropyridines were the reduction by metals or complex hydrides and the site-selective replacement by hydrazine followed by dehydrogenation-dediazotation or dehydrochlorination-dediazotation. To introduce an extra fluorine atom, a suitable precursor was metalated and chlorinated before being subjected to a chlorine/ fluorine displacement process.
