The title compound was synthesized from methyl 4-(3-bromophenyl)-1,4,5,6-tetrahydrocyclopenta[b]pyrrole-2-carboxylate (0.315 g, 0.98 mmol) and lithium hydroxide (0.415 g, 9.9 mmol), according to General Procedure 7. A 1:1 mixture of THF and methanol (8 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 the title compound. 0.119 g (40% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 2.16 (ddt, J=12.67, 8.50, 6.30, 6.30 Hz, 1H), 2.67-2.93 (m, 3H), 4.13 (t, J=7.20 Hz, 1H), 6.54 (s, 1H), 7.11-7.17 (m, 2H), 7.26-7.32 (m, 2H); LCMS (ESI+) 328.0 (M+Na); HPLC (UV=93.7%), (ELSD=99.9%).
