Versuchsvorschrift

The title compound was synthesized from methyl 4-(3-(furan-2-yl)benzyl)-1,4,5,6-tetrahydrocyclopenta[b]pyrrole-2-carboxylate (0.024 g, 0.075 mmol) and lithium hydroxide (0.032 g, 0.76 mmol), according to General Procedure 7. A 1:1 mixture of methanol (MeOH) and THF (1.5 mL) was used. The resulting product was purified by reverse phase HPLC, eluting with a gradient of 40-100% MeOH: water (with 0.1% formic acid) to afford a light pink solid: 14 mg, 61% yield. LCMS-MS (ESI−) 306.0 (M−H); HPLC (UV=93.7%), (ELSD=100%).
