Allylamine → 2-Allylamino-5,6-diphenylpyrazine

Participants

Reaction Steps

To a solution of 1.00 g of 2-chloro-5,6-diphenylpyrazine in 10 ml of methanol, 2.14 g of allylamine was added and the mixture was reacted in a sealed tube at 80° C. for 41 hours, followed by stirring at room temperature for 54 hours. After the solvent was evaporated under reduced pressure, the reaction solution was combined with water, extracted with chloroform, dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to obtain 330 mg of the desired compound as a pale yellow crystal having a melting point of 97 to 100° C.
