| abstract | 5-Cyano-1-hydrocarbylpyrrole-2-acetic acid is converted to 5-acyl-1-hydrocarbylpyrrole-2-acetic acid by reaction with a Grignard reagent followed by hydrolysis. The cyano compound, novel per se, is produced by reacting 1-hydrocarbyl-2-(2',2',2'-trihalo-1'-hydroxyethyl)pyrrole with a cyanating reagent under basic conditions. The latter pyrrole is in turn formed by reacting 1-hydrocarbylpyrrole with trihaloacetaldehyde such as chloral, preferably in the presence of added organic acid catalyst.n[US4238396A] |
