반응 단계
Following General Procedure B′ and using 4methylphenylacetic acid (Aldrich) and D,L-alanine isobutyl ester hydrochloride (from Example B′ above), the title compound was prepared as a solid having a melting point of 102°-104° C. The reaction was monitored by tlc on silica gel (Rf=0.6 in 33% ethyl acetate/hexanes) and purification was by extraction with Et2O followed by washes with aqueous K2CO3 and aqueous HCl.
