Procedure

The 2-hydroxymethylene-1-indanone is then reacted with the appropriate nitrogen compound e.g. ammonium acetate, dimethyl amine, monomethyl amine or aminoethanol, in ethanol or any other suitable solvent to yield a 2-aminomethylene-1-indanone which is then dried and recrystallized from benzene or any other suitable solvent.
