The present invention is concerned with the formation of amide bonds. More specifica lly, the present invention, relates to processes for the manufacture of organogellant compounds (OG) as depicted below wherein L is selected from C2-C20 alkyl, C6-C20 aryl, C7-C20 alkylaryl, R1 are side chain substituents and one of X1, X2 is nitrogen and the other two are carbon. Processes of the present invention employ reaction mixtures with beneficial flow characteristics allowing sufficient agitation of all parts of these reaction mixtures and thus achieving adequate mixing of reaction partners and/or dissipation of heat. The beneficial flow characteristics are achieved by using suitable activation for coupling the terminal pyridine-carboxylic acid.
