4′-[5-(Chloromethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Intermediate 45) (50 mg) was added to a freshly prepared sodium methoxide solution (0.08M, 12 ml), and the reaction stirred at room temperature for 96 hours. The reaction was partitioned between ethyl acetate and water, the organic phase dried (sodium sulphate) and reduced to dryness under vacuum. The residue was applied to a bond-elut (silica, 5 g) and eluted with an ethyl acetate/cyclohexane gradient. The product fractions were reduced to dryness under vacuum and further purified by HPLC, to give after evaporation of the solvent, N-cyclopropyl-4′-[5-(methoxymethyl)-1,3,4-oxadiazol-2-yl]-6-methyl-1,1′-biphenyl-3-carboxamide.
