Procedure

Following General Procedure C and using 2-pyridylacetic acid hydrochloride (Aldrich) 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=137-139° C.). The reaction was monitored by tlc (Rf=0.4 in 8% MeOH/CHCl3) and the product was purified by silica gel chromatography using 8% MeOH/CHCl3 as the eluent, followed by recrystallization from 1-chlorobutane/acetonitrile.
