Participants

Reaction Steps

Acetic acid anhydride (133 mg; 1.3 mmol) solved in dichloromethane (2 ml) was added dropwise to a mixture of (1,4-diaza-bicyclo[3.2.2]non-4-yl)-5-(4-aminophenyl)-furan-2-yl-methanone and dichloromethane (10 ml) at room temperature. The mixture was allowed to stir for 4 hours. Aqueous sodium hydroxide (20 ml; 1M) was added followed by extraction with dichloromethane (3×20 ml). The crude mixture was purified by silica gel chromatography, using a mixture of dichloromethane:methanol (4:1) and 2% methanol as eluent. The product was isolated as the free base. Mp. 113° C.
