F[C:2]1[CH:7]=[CH:6][CH:5]=[CH:4][C:3]=1[N+:8]([O-:10])=[O:9].[CH3:11][O:12][CH2:13][CH2:14][NH2:15]>C(O)CCC>[CH3:11][O:12][CH2:13][CH2:14][NH:15][C:2]1[CH:7]=[CH:6][CH:5]=[CH:4][C:3]=1[N+:8]([O-:10])=[O:9]To 28.2g of 2-fluoronitrobenzene in 70ml of n-butanol 30.0g of 2-methoxyethylamine were added and the mixture refluxed overnight to give a dark red solution. After cooling the n-butanol was evaporated off and the product extracted into diethyl ether. The diethyl ether was then washed twice with dilute (aqueous) hydrochloric acid, once with dilute (aqueous) sodium carbonate and once with brine. The ether was then dried using magnesium sulphate and evaporated off to give 35g of 2-(2-methoxyethylamino)nitrobenzene as a red liquid.
