Abstract
Methyl derivatives of pyrimido[1,2-a]indol-2-one were obtained by the reaction of 2,3,3-trimethyl-3H-indole salts with acrylamide in a proton-containing solvent. The products were condensed with aromatic aldehydes. The interconversion of pyrimido[1,2-a]indol-2-ones and 1-(2-carbamoylethyl)-3H-indolium salts under the influence of acids and bases was studied.
