Procedure

4-(3-Benzyl-1,2,4-oxadiazol-5-yl)-2-bromo-1-trifluoroacetylaminobenzene and (R)-1-(N-benzyloxycarbonylpyrrolidin-2-yl)-3-hydroxypropene were used. Chromatography using elution with 5% either in methylene chloride afforded the title compound (88%) as a thick yellow oil: R1 =0.32 (CHCl3); LRMS (m/z, relative intensity) 669 (M+, 25).
