Acetic Anhydride → HCID 86594879, compound

Participants

Reaction Steps

Palladium on carbon (10%; 10 mg) was added to a solution of 1-(4-chloro-2-nitro-phenyl)piperidine-4-carboxylic acid [4-(3-dimethylaminopyrrolidin-1-yl)phenyl]methylamide (50 mg) in glacial acetic acid (5 ml). The solution was stirred under a hydrogen atmosphere (1 bar), and acetic anhydride (14 μl) was added. After one hour, further acetic anhydride (6 μl) were added and the mixture was stirred for 15 minutes. The suspension was filtered and the filtrate was concentrated. The residue was purified by chromatography (silica gel, eluent: ethyl acetate/ammonia (7N in methanol)). This resulted in the product with the molecular weight of 498.07 (C27H36ClN5O2); MS (ESI): 498 (M+H+).
