실험 절차

Following General Procedure A and using 3,5-difluorophenylacetic acid (Aldrich) and (S)-2-(1-aminoethyl)-5(R,S)-ethoxycarbonyl-2-oxazoline (Example F), the title compound was prepared as a semisolid. The reaction was monitored by tlc (Rf=0.3 in 5% MeOH/CHCl3) and the product was purified by silica gel chromatography using 5% MeOH/CHCl3 as the eluent.
