反応手順
4′-[5-(Azidomethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Intermediate 44) (40 mg), triethylamine (0.051 ml) and ethyl 2-cyclopropylethanimidate hydrochloride (23 mg) in ethanol (3 ml) were heated at 80° C. for 16 hours. The ethanol was removed under vacuum, the residue applied to a bond-elut (silica) and eluted with an ethyl acetate/cyclohexane gradient. Evaporation of the solvent from the product fractions gave N-cyclopropyl-4′-[5-(cyclopropylmethyl)-1,3,4-oxadiazol-2-yl]-6-methyl-1,1′-biphenyl-3-carboxamide.
