4-Butoxybenzoic acid → 4-Butoxybenzoic acid

Participants

Reaction Steps

4-Butoxy-N-[4-(3-oxopyrrolidin-1-yl)-phenyl]benzamide was obtained using 4-butoxybenzoic acid in an analogous way. Likewise, 4-butoxybenzoic acid and 4-(1,4-dioxa-7-azaspiro[4.4]non-7-yl)-3-fluorophenylamine initially resulted in 4-butoxy-N-[4-(1,4-dioxa-7-azaspiro[4.4]non-7-yl)-3-fluorophenyl]benzamide which, after methylation by method F and treatment with para-toluenesulfonic acid as described above, afforded 4-butoxy-N-[3-fluoro-4-(3-oxopyrrolidin-1-yl)phenyl]benzamide.
