実験手順
The procedure for the preparation of [2-(3-cyclopropyl-2,4-dioxo-3,4-dihydro-2H-quinazolin-1-ylmethyl)-1-(4-hydroxy-butyl)-1H-benzoimidazol-5-ylmethyl]-carbamic acid tert-butyl ester was followed (reaction time 3 hrs.) starting from 2,2-dimethyl-propionic acid 4-[5-(tert-butoxycarbonylamino-methyl)-2-(3-vinyl-indazol-1-ylmethyl)-benzoimidazol-1-yl]-butyl ester (215 mg, 0.384 mmol). Purification by flash chromatography (eluent 3%, 4% methanol in DCM) afforded [1-(4-hydroxy-butyl)-2-(3-vinyl-indazol-1-ylmethyl)-1H-benzoimidazol-5-ylmethyl]-carbamic acid tert-butyl ester (136 mg, 74%) as a white foam:
