The title compound was synthesized in two steps. First, methyl 4-oxo-1,4,5,6-tetrahydrocyclopenta[b]pyrrole-2-carboxylate (0.40 g, 2.23 mmol) was reacted with 3-chloro-5-fluorobenzylmagnesium chloride ((0.25 M in diethyl ether, 23.0 mL, 5.6 mmol) according to General Procedure 3. The resulting exo-olefin ((E)-methyl 4-(3-chloro-5-fluorobenzylidene)-1,4,5,6-tetrahydrocyclopenta[b]pyrrole-2-carboxylate) was then converted to the title compound by hydrogenation according to General Procedure 6 (with PtO2). The crude product was purified by column chromatography (Isco CombiFlash) eluting with a gradient of 0-100% EtOAc/heptane to afford the title compound. 0.045 g The material was taken on to hydrolysis in impure form.
