Reaction Steps
The same procedures as in Example 3 were repeated using 2,3-diphenyl-5,6-dihydropyrazine and m-anisaldehyde. 2,3-Diphenyl-5-(m-methoxybenzyl)pyrazine was obtained as colorless prisms, m.p. 65°-66° C. (recrystallized from methanol-water). Physical properties of the product support a chemical structure of the below formula (IX).
