Participants

Reaction Steps

Following General Procedure A above using N-(3,5-difluorophenylacetyl)-L-alanine (Example B) and 3-amino-2,3-dihydro-1-ethyl-5-phenyl-1H-1,4-benzodiazepin-2-one (prepared as described in Example 8-X using ethyl iodide), the title compound was prepared as a solid having a melting point of 155-158° C. The reaction was monitored by tlc on silica gel (Rf=0.48 in 10% methanol/dichloromethane) and purification was by silica gel chromatography using 10% methanol/dichloromethane as the eluant followed by recrystallization from diethyl ether.
