Procedure

1.3 g (2.86 mMol) of tert.-butyl 4'-[(6-amino-2-n-butyl-benzimidazol-1-yl)-methyl]biphenyl-2-CARBOXYLATE, 0.6 g (5.35 mMol) of hexahydrohomophthalic acid anhydride and 5 ml of pyridine are refluxed with stirring for 3 hours. Then the pyridine is removed by rotary evaporation in vacuo, the residue is crystallised from acetone, washed with acetone and dried in vacuo at 70° C.
