| abstract | NEW MATERIAL:A pyridine compound of formula I (R 1 , R 2 are H, lower alkyl; R 3 is halogen; R 4 is isopropyl, tert.-butyl). n EXAMPLE: 4-(2-Chloronicotinoyl)-2,6-di-tert.-butylphenol. n USE: An intermediate of pyrazolopyridines having anti-inflammatory, analgesic, antipyretic, antiarthritic, antirheumatic and antiplatelet action. n PREPARATION: For example, a compound of formula II (X is halogen) is allowed to react with a compound of formula III under usual Friedel-Craft reaction conditions, namely in an inert solvent (such as dichloroethane or nitrobenzene) in the presence of a catalyst such as aluminum trichloride at a temperature of ice-cooling to the boiling point of the solvent to give the compound of formula I. n COPYRIGHT: (C)1989,JPO&Japio |
