1'-[(6-chloro-1H-indol-3-yl)carbonyl]-5-fluoro-3H-spiro[2-benzofuran-1,4'-piperidin]-3-one → 1'-({6-Chloro-1-[(5-cyclopropyl-2-methyl-1,3-oxazol-4-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 5-cyclopropyl-2-methyl-oxazol-4-ylmethyl ester (prepared by mesylation of (5-cyclopropyl-2-methyl-oxazol-4-yl)-methanol) gave the title compound. ES-MS m/e (%): 534.2 (M+H+).
