YieldReaction ConditionsOperation in experiment
94% 2.87 mL NaOH (5 N) in 2.30 mL methanol was added to N-tosyl-3-methylacetatel pyrrole 10 (260.8 mg, 0.89 mmol) and refluxed for 2 h. The methanol was removed and the residue was washed with diethyl ether and acidified by using a gradient of aqueous HCl in the range of 5 N-0.5 N to pH 3, and finally extracted four times with diethyl ether. The solution was dried over Na2SO4 anhydrous. After removal of the solvent, 3-acetic acid pyrrole 11 was obtained as a white solid (yield 105 mg, 0.84 mmol, 94%). The product was recognized by 1H NMR spectra [16] .
