The title compound was prepared from 3-(4-fluorophenethyl)-6-[1-(4-fluorophenyl)-2-(1-methylimidazol-5-yl)ethoxy]pyridin-2-carboxylic acid by a similar route to that described for the preparation of tert-butyl (2S)-2-{3-(4-fluorophenethyl)-6-[1-(4-fluorophenyl)-2-(1-methylimidazol-5-yl)ethoxy]pyrid-2-oylamino}-4-methylsulfanylbutyrate but using L-methionine cyclopentyl ester rather than L-methionine-tert-butyl ester.
