실험 절차
To a solution of (5-methyl-1H-pyrrol-3-yl)-acetic acid (8.2 mmol) in TFA (6 mL) at 0° C. was added triethyl orthoformate (6 mL), it was then at 0° C. for 10 mins and at rt for 0.5 hours. The reaction was poured into water, extracted with ethyl acetate, dried and concentrated. The residue was purified on a silica gel column to give 1.15 g (84%) of (2-formyl-5-methyl-1H-pyrrol-3-yl) acetic acid.
