The reaction vessel was then sealed and placed into a 90 C. oil bath for overnight stirring and heating. After about 18 hours the reaction mixture was cooled to ambient temperature and then diluted with EtOAc. The organics were washed with brine (*4), dried over sodium sulfate, filtered, and concentrated under reduced pressure to give an oil. This oil was subject to silica gel chromatography eluding with 10-60% EtOAc in hexanes to provide methyl 4'-{(1R)-1-[(tert-butoxycarbonyl)amino]ethyl }-3-fluoro-1,1'-biphenyl-2-carboxylate (205 mg), found to be pure by LC/MS and proton NMR.
