YieldReaction ConditionsOperation in experiment
24% With triethylamine; In tetrahydrofuran; at 70℃; for 15.0h; General procedure: Compounds 1-6 were prepared according to conventional organic synthesis methods. 3-Chloropyrazine-2-carboxamide (1.27 mmol) was dissolved in THF (20 mL) in a round bottom flask and after that treated with two equivalents of the corresponding benzylamine and an equimolar amount of triethylamine. The reaction was conducted with continuous stirring and heating (70 C) under reflux in an oil bath for 15 h. Compounds 7-15 were synthesised using a microwave reactor with a focused field. 3-Chloropyrazine-2-carboxamide (1.27 mmol) was put into a thick-walled tube together with the corresponding benzylamine (2.54 mmol), pyridine (1.27 mmol), methanol (approx. 5 mL) and a magnetic stir bar and then sealed with a special cap. The reaction parameters were set according to the previously published paper as follows-140 C, 30 min, 200 W [29]. Reaction progress was checked by TLC (hexane:ethyl acetate-1:1). Regardless of the synthesis method used,all reaction mixtures were adsorbed on silica and subjected to preparative flash chromatography (hexane and ethyl acetate, gradient elution, detection wavelengths 260 nm and 280 nm). Products were recrystallized from ethanol or ethanol and water if necessary. All final substances were chemically characterized (1H-NMR, 13C-NMR, IR, melting point and elemental analysis).

67% With acetic acid; at 110℃; for 4h; General procedure: The starting materials 1 and 2 were commercially available (Energy Chemical, Shanghai, China).Compound 2 (3.72 mmol) was added to a stirred solution of compound 1 (3.38 mmol) in glacial aceticacid (10 mL). The reaction mixture was then stirred at 110 C for 4 h. After completion of the reaction,the solvent was evaporated, and the residue was purified on a silica gel column chromatography andeluted with ethyl acetate/petroleum ether (bp 60-90 C) (1:3, v/v) to give compounds 3.
