| titleOfInvention |
Production of 5-methyl-n-(methyl aryl)-2-pyrrolidone, 5-methyl-n-(methyl cycloalkyl)-2-pyrrolidone and 5- methyl-n-alkyl-2-pyrrolidone by reductive amination of leuvlinic acid esters with cyano compounds |
| abstract |
This invention relates to a process for producing 5-methyl-1-R-2-pyrrolidone or 5-methyl-2-pyrrolidone, wherein R is a hydrocarbyl or substituted hydrocarbyl, by reductive amination of levulinic acid utilizing a metal catalyst, which may be optionally supported. |
