Procedure

A mixture of (5S,7S)-5-(4-cyanobenzyl)-3-(3,5-dichlorophenyl)-7-amino-1,3-diazabicyclo[3.3.0]octane-2,4-dione (200 mg), malonamic acid (59.5 mg), EDC (112 mg), HOBT (97.5 mg) and DIEA (168 μL) in THF (5 mL) was stirred overnight at room temperature. The reaction mixture was evaporated. The residue was dissolved in EtOAc and the resulting solution was washed with water, saturated aqueous NaHCO3 solution, brine, dried (Na2SO4) and concentrated to give 212 mg of the titled compound. MS (m/z) 500 (MH+).
