実験手順

4′-[5-(Aminomethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Example 53) (30 mg) was mixed with α-toluenesulphonyl chloride (33 mg) in pyridine (6 ml) at 0° C. and the reaction stirred at room temperature for 72 hours. Further α-toluenesulphonyl chloride (66 mg) in pyridine (3 ml) was added and stirring continued for 18 hours. The reaction was diluted with DCM and washed with hydrochloric acid (2N, 4×5 ml) and then water (5 ml). The organic phase was reduced to dryness under vacuum and the residue purified by HPLC to give after evaporation of the solvents 4′-(5-{[(benzylsulfonyl)amino]methyl}-1,3,4-oxadiazol-2-yl)-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide.
