The title compound was prepared as in Example X from N-methyl benzimidoyl chloride (6.87 g, 44.8 mmole), chlorosulfonic acid (0.52 g, 4.5 mmole), methyl 1,4-dimethyl-1H-pyrrole-2-acetate (7.43 g, 44.5 mmole), and 70% perchloric acid (7.0 g, 49 mmole) to yield 10.4 g (61%) as a yellow solid, m.p. 145°-147° C. (dec).
