Methanol → 6-(3-Methoxybenzyl)-1,4,5,6-tetrahydrocyclopenta[b]pyrrole-2-carboxylic acid

Participants

Reaction Steps

The title compound was synthesized from methyl 6-(3-methoxybenzyl)-1,4,5,6-tetrahydrocyclopenta[b]pyrrole-2-carboxylate (127 mg, 0.45 mmol) and lithium hydroxide (188 mg, 4.50 mmol in 1 mL water), according to General Procedure 7. A 1:1 mixture of methanol (MeOH) and THF (2 mL) was used. The resulting product was purified by chromatography, eluting with heptane-EtOAc, gradient 0 to 50% EtOAc. 80 mg. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 2.10-2.21 (m, 1H) 2.53-2.76 (m, 4H) 2.91-2.99 (m, 1H) 3.34-3.44 (m, 1H) 3.82 (s, 3H) 6.72-6.77 (m, 2H) 6.78-6.86 (m, 2H) 7.24-7.31 (m, 2H) 8.28 (br. s., 1H). LCMS m/e 272 (M+H). Purity>99% (HPLC).
