Reaction Steps

A solution of 6-[4-(2-methoxycarbonylphenyl)benzyl]-8-(3,5-dichlorophenyl)-1,8-diazabicyclo[4.3.0]nonane-7,9-dione (0.141 g) in MeOH/H2O (5/1 mL) containing NaOH (0.087 g) was heated at 50° C. for 2 h. The reaction mixture was cooled in ice and acidified with 0.5 N HCl. It was extracted with EtOAc and the extract was washed with water, brine, dried (MgSO4), filtered, and concentrated. Purification by chromatography (Silica gel: CHCl3/MeOH: 100/1 to 50/1, Chromatotron) afforded the titled compound (114 mg). MS (m/z) 531(M++Na).
