| abstract |
The present invention relates to a process for producing A 1 - A 2b Receptor, or a compound of formula A1, which may be useful for treating a condition or disorder that is alleviated by the inhibition of an A 2a receptor, wherein A is Cy 1 or Het A ; Fully saturated or partially unsaturated carbocyclic ring system, optionally substituted with one or more R 4a substituents, wherein Cy 1 is a 5 to 14 membered ring containing 1, 2 or 3 rings; Het A is a 5- to 14-membered heterocyclic group which may be aromatic, fully saturated or partially unsaturated, containing one or more heteroatoms selected from O, S and N, wherein 1, 2 or 3 And optionally substituted with one or more R < 4b > substituents; B is Cy 2 or Het B ; Wherein Cy 2 is a three to ten membered aromatic, fully saturated or partially unsaturated carbocyclic ring system comprising one or two rings, wherein the Cy 2 group is optionally substituted with one or more R 4c substituents; Het B is a 3 to 10 membered heterocyclic group which may be aromatic, fully saturated or partially unsaturated, containing one or more heteroatoms selected from O, S and N, said heterocyclic group being optionally substituted with 1 Or two rings, wherein the Het B group is optionally substituted with one or more R 4d substituents. |
