Procedure
Following General Procedure A above using N-(3,5-difluorophenylacetyl)-L-alanine (Example B) and 3-amino-2,3-dihydro-1-methyl-5-phenyl-1H-1,4-benzodiazepin-2-one (prepared as described in Bock M. G.; DiPardo, R. M.; Evans, B. E.; Rittle, K. E.; Veber, D. F.; Freidinger, R. M.; Hirshfield, J.; Springer, J. P. J. Org. Chem. 1987, 52, 3232), the title compound was prepared as a solid having a melting point of 152-160° C. The reaction was monitored by tlc on silica gel (Rf=0.15 in 50% ethyl acetate/hexanes) and purification was by silica gel chromatography.
