Reaction Steps

A mixture of 115 mg of rac-toluene-4-sulfonic acid (1R*,2R*,4R*)-2-(2-hydroxy-5-phenyl-bicyclo[2.2.2]oct-5-en-2-yl)-ethyl ester and 55 mg of [3-(1H-benzoimidazol-2-yl)-propyl]-methyl-amine in 2 mL of DIPEA was heated to 110° C. for 30 min. The reaction mixture was cooled to rt, quenched with MeOH-water and extracted with EtOAc. The organic phase was separated, dried and evaporated and the residue was purified by CC with EtOAc-MeOH (3:1) to give 34 mg of rac-(1R*,2R*,4R*)-2-(2-{[3-(1H-benzoimidazol-2-yl)-propyl]-methyl-amino}-ethyl)-5-phenyl-bicyclo[2.2.2]oct-5-en-2-ol as beige foam.
