Reaction Steps

Following General Procedure C and using 3,5-difluorophenylacetic acid (Oakwood) and N-(L-alaninyl)-L-phenylalanine methyl ester hydrochloride (prepared from N-BOC-L-alanine (Sigma) and L-phenylalanine methyl ester hydrochloride (Sigma) using General Procedure C, followed by removal of the BOC-group using General Procedure P), the title compound was prepared as a solid (mp=173-175° C.). The reaction was monitored by tlc (Rf=0.6 in 10% MeOH/CHCl3) and the product was purified by silica gel chromatography using 4% MeOH/CHCl3 as the eluent, followed by recrystallization from 1-chlorobutane/acetonitrile.
