Versuchsvorschrift
Methyl 4-(3-tert-butoxy-3-oxopropyl)-1H-pyrrole-2-carboxylate (473 g, 1.87 mmol) was treated for about 12 h at rt with 4 N HCl (5 mL). The solvent was removed and the white solid product was dried to give 350 mg (95%) of 3-(5-(methoxycarbonyl)-1H-pyrrol-3-yl)propanoic acid. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 2.64 (t, J=7.35 Hz, 2H), 2.84 (t, J=7.35 Hz, 2H), 3.85 (s, 3H), 6.79 (dd, J=6.66, 2.22 Hz, 2H), 9.08 (br s, 1H); LCMS-MS (ESI+) 198.2 (M+H).
