Synthesized from 3-{4-[2-(tert-butoxycarbonyl-heptyl-amino)-ethyl]-phenyl}-2-hydroxy-propionic acid ethyl ester using a procedure analogous to that used for Example 47 and substituting methyl iodide as the electrophile to give 3-{4-[2-(tert-butoxycarbonyl-heptyl-amino)-ethyl]-phenyl}-2-methoxy-propionic acid methyl ester as a clear oil containing a mixture of methyl and ethyl ester (48 mg, 18%).
