Reaction Steps

Following General Procedure B and using 2-chlorobenzothiazole (Aldrich) and L-alanine (Aldrich), N-(benzothiazol-2-yl)-L-alanine was prepared. This compound was then coupled to L-norleucine methyl ester hydrochloride (Sigma) using General Procedure D (without the 1N HCl wash) to provide for the title compound as a solid (mp=99-120° C.). The latter reaction was monitored by tlc (Rf=0.42 in 1:1 EtOAc:Hexanes) and the product was purified by preparative plate chromatography using 1:1 EtOAc:Hexanes and 5:95 MeOH:dichloromethane as the eluent.
