Procedure

To a solution of POCl3 (0.1 mL) and DMF (0.3 mL) was added after 45 minutes a solution of 5-(4-cyanobenzyl)-3-[3-chloro-5-(1-pyrrolyl)-phenyl]-1,3-diazabicyclo[3.3.0]octane-2,4-dione (0.22 g) in DMF (0.5 mL). After 1 hour at room temperature, the reaction mixture was diluted with water (2 mL) and stirred. After 30 minutes, the mixture was diluted with CH2Cl2 and satd. NaHCO3. The organic layer was collected, washed with brine, dried (Na2SO4), filtered and concentrated. Purification by chromatography (silica gel: EtOAc/hexane: 1/3, Chromatotron) afforded 0.091 g of the titled compound. MS (m/z) 459 (MH+). mp 109.7° C.
