反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: N-Ethyl-N-(2-aminobenzyl)amine (707 mg, 4.7 mmol) in DMF (11 ml) was treated with 6-chloropyridazin-3-amide (4.7 mmol) followed by diisopropylethylamine (15.4 mol) and the reaction stirred at 140° under argon for 24 hours. The reaction was evaporated in vacuo (cold-finger) and the residue partitioned between water and ethyl acetate. The combined organic extracts were dried and evaporated to give a brown gum. The gum was purified by medium pressure chromatography to give 6-(N-ethyl-N-(2-aminobenzyl)amino)-pyridazine-3-carboxamide (500 mg, 30%). The reaction was evaporated in vacuo (cold-finger) the residue partitioned between water and ethyl acetate The combined organic extracts were dried evaporated to give a brown gum The gum was purified by medium pressure chromatography

実験手順: N-Ethyl-N-(2-nitrobenzyl)amine (4 g, 22 mmol) in ethanol (100 ml) was treated with 10% palladium-on-carbon (180 mg) and hydrogenated at N.T.P. for 2 hours. When uptake of hydrogen had ceased the reaction was filtered through Celite and evaporated to give N-ethyl-N-(2-aminobenzyl)amine (3.3 g, 100%). was filtered through Celite evaporated
