4′-[5-(Azidomethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Intermediate 44) (27.8 mg) and palladium on carbon (10% w/w, 5 mg) in ethanol (5 ml) were hydrogenated under 1 Atm. of hydrogen for 2 hours. The reaction was filtered through celite, the filtrate reduced to dryness under vacuum and the residue applied to a bond-elut (silica, 4 g). The column was eluted with chloroform, ether, ethyl acetate, and methanol. The methanol fraction was reduced to dryness under vacuum to give 4′-[5-(aminomethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide.
