A process for 5-aroylation of 1,2-dihydro-3H-pyrrolo [1,2-a]pyrrole-1-carboxylic esters and nitriles by reacting a pyrrolo pyrrole
with an aroyl morpholide
and an inorganic acid chloride in an inert aprotic solvent; followed by treatment with weak or strong base to form:
The nitrile (V) can be hydrolyzed to the acid (III).
