(1-methyl-1H-imidazol-5-yl)methanol → 1'-({6-Chloro-1-[(1-methyl-1H-imidazol-5-yl)methyl]-1H-indol-3-yl}carbonyl)-5-fluoro-3H-spiro[2-benzofuran-1,4'-piperidin]-3-one

Participants

Reaction Steps

Following the general procedure III as described above, the alkylation of 1′-[(6-chloro-1H-indol-3-yl)carbonyl]-5-fluoro-3H-spiro[2-benzofuran-1,4′-piperidin]-3-one (prepared according to example 19) with methanesulfonic acid 3-methyl-3H-imidazol-4-ylmethyl ester (prepared by mesylation of the commercially available (3-methyl-3H-imidazol-4-yl)-methanol) gave the title compound. ES-MS m/e (%): 493.1(M+H+).
