摘要:
The present invention provides a process for preparing a compound of the general formula (I): 1 wherein R1 to R5 are independently selected from hydrogen, halogen, C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl or C1-6 alkoxy, all optionally substituted by one or more of halogen, hydroxy and aryl groups, as well as being independently selected from amino, mono- or disubstituted amino, alkenyloxy, acyl, acyloxy, cyano, nitro, aryl and alkylthio groups, which process comprises reacting a compound of the general formula (II): 2 wherein R1 to R5 are as defined in formula (I), with aminoguanidine bicarbonate in a mixture of a water-soluble solvent and polyphosphoric acid.
摘要:
Cyano and carboxy derivatives of substituted styrenes are inhibitors of tumor necrosis factor .alpha., nuclear factor .kappa.B, and phosphodiesterase and can be used to combat cachexia, endotoxic shock, retrovirus replication, asthma, and inflammatory conditions. A typical embodiment is 3,3-bis-(3,4-dimethoxyphenyl)acrylonitrile.
