Procedure

The methylation procedure of Example 77A is repeated, except that an equivalent quantity of ethyl 5-(2′-methylbenzoyl)-1,4-dimethylpyrrole-2-acetate (from Example 92) is methylated instead of the ethyl 5-(p-chlorobenzoyl)-1,4-dimethylpyrrole-2-acetate used in Example 77A, to yield ethyl 5-(2′-methylbenzoyl)-1,4, α-trimethylpyrrole-2-acetate.
