Irradiation of 2,5-bis(methoxycarbonyl)-3,6-dimethylpyrazine in diethyl ether with a 450-W high-pressure mercury lamp (330 nm) gave two significant photoproducts 2-hydroxy-5-methoxycarbonyl-3,6-dimethylpyrazine and l-(l -ethoxy-ethyl)2,5-dimethoxycarbonyl-3,6-dimethyl-l, 4-dihydropyrazine (74). Similar products were isolated when tetrahydrofuran was used as solvent. Corresponding reactions were observed with 2,5-bis(ethoxycarbonyl)-3,6-dimethylpyrazine, 2,5-diacetyl-3,6-dimethylpyrazine, and 2,5-dibenzoyl-3,6-dimethylpyrazine. The mechanism of these reactions were investigated and the initial stage was found to be... [Pg.300]

Among conversions of the amino to the azido group, 4-amino-2-phenyl-5-phenylazotriazole, treated in turn with hydrochloric acid, sodium nitrite, and sodium azide, produced 4-azido-2-phenyl-5-phenylazotriazole (0°C, 30 min, 76%) (70BCJ3587) 4-amino-5-methoxycarbonyl-3-phenyltriazole, similarly treated, gave the 4-azido analog (82%) (83BSB913).
