Procedure

Following General Procedure I above using 3,5-difluoromandelic acid (Lancaster) and 3-(L-alaninyl)-amino-2,4-dioxo-1,5-bis-(2,2-dimethylpropyl)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepine hydrochloride (Example 8-V), the title compound was prepared as a white solid (melting point=116–126° C.). Purification was by flash chromatography eluting with CH2Cl2/EtOAc (1:1 gradient to 2:3). Rf=0.54 and 0.40 (CH2Cl2/EtOAc, 1:1).
