Patent ID: 7019094

Claim:
An intermediate product suitable for synthesis of heterocyclic compounds which is a compound of the general formula I coupled to a solid polymeric support through the R 4 group R 1 groups represent the same or different groups chosen from lower alkyl with 1 to 6 carbon atoms, cycloalkyl with 3 to 6 carbon atoms in the ring, heterocyclic compounds including one or more heteroatoms, benzyl groups; two R 1 groups together can be included in heterocyclic ring containing one or more nitrogen atoms; R 2 represents H or a lower alkyl with 1 to 6 carbon atoms; R 4 represents unsubstituted or substituted aromatic ring(s), unsubstituted or substituted heteroaromatic ring(s), with one or more heteroatoms, or OR 5 ; when R 4 is unsubstituted or substituted aromatic ring(s), unsubstituted or substituted heteroaromatic ring(s), R 3 represents H, alkyl, unsubstituted or substituted aromatic ring, unsubstituted or substituted heteroaromatic ring with one or more heteroatoms, when R 4 is OR 5 , R 3 is CN, NCOR 5 , or NCOOR 5 ; the R 5 groups, which can be the same or different, represent alkyl, benzyl, unsubstituted or substituted aromatic ring(s), unsubstituted or substituted heteroaromatic ring(s) with one or more heteroatoms.
