実験手順

Following General Procedure D and using N-(3,5-dichlorophenyl)-D,L-alanine and L-norleucine N-methyl amide (prepared by coupling BOC-L-norleucine (Bachem) with methylamine (Aldrich) using General Procedure E, followed by removal of the BOC group using General Procedure F), the title compound was prepared. The reaction was monitored by tlc (Rf=0.25 in 3% methanol/dichloromethane) and purification of this compound was by thin layer chromatography with 3% methanol/dichloromethane.
