YieldReaction ConditionsOperation in experiment
75% In ethanol; for 8h;Inert atmosphere; Reflux; 4-Amino-1,8-naphthalic anhydride (10 mmol, 2.13 g) was dissolved in ethanol under nitrogen atmosphere and brought to reflux.1-butylamine was then added and the mixture was further refluxed for 8 h. After cooling down, the solvent was removed under reduced pressure, and the crude product was purified by silica gel column chromatography using DCM/ethyl acetate (2/1, v/v) as the eluent (75% yield).1H NMR (CDCl3, 500 MHz): delta 8.60 (d, 1H, C(O)CCHCHCH), 8.42 (d, 1H, C(O)CCHCHCH), 8.10 (d, 1H C(O)CCHCHCH), 7.66 (t, 1 H, C(O)CCHCH), 6.89 (d, 1H, C(O)CCHCH), 4.94 (s, 2H, NH2), 4.18 (t, 2H, CH2CH2CH2CH3), 1.71 (m, 2H, CH2CH2CH2CH3), 1.45 (m, 2H, CH2CH2CH2CH3), 0.97 (s, 3H, CH2CH2CH2CH3).
74% In N,N-dimethyl-formamide; at 110℃; for 5h; 4-Aminonaphthalene anhydride (430 mg, 2 mmol), 4 mL of DMF and n-butylamine (150 mg, 2 mmol) were added to a 25 mL flask, and heated to 110 C for 5 h with magnetic stirring. After the reaction is over, the heating is stopped, and the solution is naturally cooled to room temperature. Pour into 100 mL of potassium hydrogen sulfate solution (5%, m/m), suction filtration, water washing, and infrared drying. Column chromatography (dichloromethane: methanol = 100:1),Obtained an orange solid 390mg,The yield was 74%.
64.3% In ethanol; for 5h;Reflux; <strong>[6492-86-0]4-amino-1,8-naphthalenedicarboxylic anhydride</strong> (0.30 g, 1.4 mmol) and CH3CH2CH2CH2N2 (0.74 g, 10 mmol) were suspended in 20 mL of absolute ethanol and refluxed for 5 hours, concentrated to 5 mL, Wash cake,After drying, a yellow powder, 0.24 g, was obtained in a yield of 64.3%.No purification is required for the next step.
