Procedure
Following General Procedure AH above and using N-(3,5-difluorophenyl)alanine (from Example AC above) and iso-butanol, the title compound was prepared as an oil. The reaction was monitored by tlc on silica gel (Rf=0.9 in 3% methanoulmethylene chloride) and purification was by preparative plate chromatography (silica gel using 3% methanolumethylene chloride as the eluant).
