Procedure

To a solution of 2-(2-(2,4-dichlorophenyl)hydrazono)cyclopentanone (2.2 g, 8.59 mmol) in MeCN (10 mL), H2SO4 (1.4 mL, 1.8M solution) was added and the mixture stirred at 80° C. for 16 h. The reaction mixture was cooled to room temperature, basified with saturated NaHCO3 and extracted with EtOAc (3×30 mL). The combined organic extracts were dried over Na2SO4 and concentrated in vacuo to give the crude title compound as an off-white solid (800 mg) which was used in the next step without purification.
