Reaction Steps

Sodium hydride (60%, 54 mg) was added to a solution of 3-acetylamino-2-methyl-7-nitrobenzo[b]furan (280 mg) in N,N-dimethylformamide (3 ml) at 4° C. The mixture was stirred for 30 minutes and to the mixture was added iodoethane (240 mg). The mixture was stirred at ambient temperature for 2 hours. The reaction mixture was poured into cold water and the separated oil was extracted with ethyl acetate. The extract was washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography on silica gel to give 3-(N-acetyl-N-ethylamino)-2-methyl-7-nitrobenzo[b]furan as a crystalline solid (310 mg).
