PROCEDURE

实验过程

Following General Procedure I above using cyclopropylacetic acid (Lancaster) and 3-(L-alaninyl)amino-2,4-dioxo-1,5-bis-(2-methylpropyl)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepine hydrochloride (Example 8-S), the title compound was prepared as a white solid (melting point=190-191° C.). Purification was by flash chromatography eluting with CH2Cl2/EtOAc (1:1 gradient to 3:4) and a second flash chromatography eluting with EtOAc/Toluene (7:3). Rf=0.28 (EtOAc/Toluene, 7:3).
