  • Patent number: 6372768
    Abstract: The present invention relates to 2-aminopyridine derivatives of the formula I: or pharmaceutically acceptable salts thereof, wherein A and B are each independently H, or together, A and B form a ring fused to the phenyl ring, said ring being saturated or unsaturated and containing from 5 to 7 ring member atoms, where said ring member atoms may optionally comprise from 1 to 2 heteroatoms selected independently from the group consisting of N, O or S, provided that no two adjacent ring members are heteroatoms; X is oxygen or a single bond; Y is (C1-C6)alkyl; R1 is hydrogen, (C1-C6)alkyl or a (C1-C6 alkyl) group substituted with —NR2R3 wherein R2 and R3 are either selected independently from the group consisting of H, alkyl, aryl, aralkyl or tetrahydronaphthalene, wherein said aryl group or said aryl moiety of said aralkyl group is phenyl or naphthyl, said alkyl group or said alkyl moiety of said aralkyl group contains from one to six carbon atoms and is straight-chained or branched,

  • Patent number: 6323366
    Abstract: The present invention provides a method for the preparation of a wide range of primary arylamines. The arylamines are prepared in two efficient, straightforward transformations: 1) an activated aryl group and an imine group are combined, in the presence of a transition metal catalyst, under conditions wherein the transition metal catalyst catalyzes the formation of a carbon-nitrogen bond between the activated carbon of the arene and the imine nitrogen; and 2) the resulting N-aryl imine is transformed, via any of a number of standard protocols, to the primary arylamine. The method of the invention may also be exploited in the preparation of vinylamines.
