Reaction Steps
A solution of 26.4 g of 4-amino-N,N-dimethylbenzamide in 500 ml toluene and 60 g acetonylacetone is refluxed for 16 hours under a Dean-Stark water separator. The solution is washed with water and brine, dried over MgSO4, filtered and the solvent evaporated at 60° and reduced pressure. The residue is crystallized from ether-hexane 1:1 to yield 1-(4-dimethylcarbamoylphenyl)-2,5-dimethyl-1H-pyrrole, m.p. 102°-104°.
