| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF A PIRAZI-NICO PRODUCT. |
| abstract | A procedure for the preparation of a pyrazinic product of structure I ** (See formula) ** by reaction of compounds of structures II and III, in the presence of a base, followed by treatment with a mineral acid ** (See formula) ** where, in each of the structures, R represents C1-5 alkyl or phenyl; R1 represents straight or branched chain C3-6 alkyl, straight or branched chain C3-6 hydroxyalkyl, straight or branched chain alkynyl, C1-6 phenylalkyl or indolyl-C1-6 alkyl; R2 represents chlorine or hydroxy; R3 represents hydrogen or X-sulfonyl, where X represents alkyl, aryl or arylalkyl; and R4 represents hydrogen, lower alkyl and phenyl and when R2 is chlorine, R3 is hydrogen and when R2 is hydroxy, then R3 is X-sulfonyl.
