Reaction Steps

Isoamyl nitrite (5.2 mL, 39 mmol) was added to a suspension of 3-aminopyrazine-2-carboxylic acid methyl ester (1.9 g, 12 mmol) in diiodomethane (20 mL) at 85° C., then the mixture was stirred at 100° C. for 15 hours. The reaction mixture was allowed to stand and purified by silica gel column chromatography to give 1.4 g of the title reference compound as a pale yellow solid. (Yield 44%)
