実験手順

100 mg of 6-oxo-1-(2-trimethylsilanylethoxymethyl)-5-[1-(2-trimethylsilanyl-ethoxymethyl)-1H-benzimidazol-2-yl]-1,6-dihydropyridazine-3-boronic acid (example 55), 35.5 mg of copper(II) acetate and 20 mg of imidazole are dissolved in dry pyridine, and the solution is stirred at 80° C. for 3 hours. For workup, it is diluted with 20 ml of water and extracted several times with ethyl acetate, the organic phases are dried using a silica gel cartridge, and the volatile components are distilled off. The crude product is purified by preparative RP-HPLC (0-100% acetonitrile (+0.05% formic acid) in water (+0.05% formic acid)).
