Conclusions
A method of synthesis is given for monoarylhydrazones of benzoylglyoxal, of 1-aryl-1,2-propandione, and of 1-aryl-1,2-butandiones. Cyclization of monoarylhydrazones of 1-aryl-1,2-butandiones under conditions of the Fischer reaction yielded a series of derivatives of 2-aroylindole, which on reaction with dimethyl sulfate in an alkaline medium were converted to the corresponding N-methyl derivatives of 2-aroylindole.
