Methyl 5-[cyanohydroxy(4-methylphenyl)methyl]-1-methylpyrrole-2-acetate (0.161 g, 0.540 mmoles) was dissolved in 30 ml of ether and shaken with 10 percent NaOH, washed with brine and dried over MgSO4. Evaporation of the ether yielded 0.130 g (86.1 percent) of methyl 1-5-(4-methylbenzoyl)pyrrole-2-acetate, mp 118°-120°. The IR was identical to an authentic sample of methyl 1-methyl-5-(4-methylbenzoyl)pyrrole-2-acetate.
