Procedure
In accordance with the method of Example 8, isopropyl 1,2-dihydro-6-methyl-3H-pyrrolo[1,2-a]pyrrole-1-carboxylate is condensed with N,N-dimethyl-p-toluamide, to produce isopropyl-5-p-toluoyl-1,2-dihydro-6-methyl-3H-pyrrolo[1,2-a]pyrrole-1-carboxylate (XI, R = CH3, R1 = p-CH3, R2 = iC3H7).
