SYNTHESIS OF CHROMOGENIC INDOLYLPHENYLDIHYDROFUROPYRIDIN-ONE COMPOUNDS ABSTRACT OF THE DISCLOSURE Chromogenic pyridine compounds having the formula: Image wherein R1, R2, R3 and R4 are each hydrogen an alkyl radical having 1 to 4 carbon atoms, or a phenyl radical, and R5 is hydrogen or an alkyl or alkoxy radical having 1 to 4 carbon atoms, are prepared in a one-vessel system without the isola- tion of intermediates. The result is a simplified, convenient procedure requiring less total reaction time which gives a considerably improved overall yield of product.
