1-Bromohexane → HCID 18537656, compound

Participants

Reaction Steps

To a suspension of sodium hydride (55 wt. %, 1.26 g) in anhydrous N,N-dimethylformamide (100 ml) was added N-[5-(4-t-butoxycarbonylaminophenoxy)-2-nitrophenyl]-N-methylcarbamate (12.1 g). The mixture was stirred at ambient temperature for several minutes. To the mixture was added hexyl bromide (6.5 g) under ice cooling and the mixture was stirred at the same temperature for 30 minutes and then at room temperature for 1.0 hour. The reaction mixture was concentrated and the residue was partitioned between ethyl acetate and water. The ethyl acetate layer was dried over anhydrous sodium sulfate and concentrated. The residue was purified by chromatography on a silica gel column using toluene/diisopropyl ether=100/7 as the eluant to give the title compound (13.8 g).
