cis-2-Oxobicyclo[4.2.0]octane-1-acetic acid ethyl ester (3.5 g, 17.01 mmol) and phenylhydrazine (1.9 mL, 18.8 mmol) were allowed to react according to the procedure of Example 2. Flash chromatography (SiO2, 10% EtOAC/petroleum ether) afforded 0.798 g (16%) of cis-1,2,2a,3,4,9-hexahydro-9bH-cyclobuta[a]carbazole-9b-acetic acid ethyl ester.
