Pyrazinecarbonyl azides

Pyrazinecarbonyl azide (165) gave 2-pyrazinecarboxanilide (166) (PhNH2, MeOCH2CH2OMe, 20°C, <12 days 86%).1130... [Pg.324]

Pyrazinecarbonyl azides may be converted into pyrazinamines (see Section 7.3.1) or into pyrazinecarboxamides or pyrazinecarboxanilides (see Section 8.4.1). In addition, two molecules of 3-(pyrrol-l-yl)-2-pyrazinecarbonyl azide (211) in warm water for 15 min have been reported to give /V,/V -bis 3-(pyrrol-l-yl)pyrazin-2-yl]urea (212) in 32% yield.94... [Pg.330]

Amino or A-BOC-amino pyrazines have been produced by Curtius degradation of pyrazinecarbonyl azides in 7-butanol (Equation 30) <1999JA8783>. [Pg.317]

Pyrazinecarbonyl azides have been made from pyrazinecarbonyl halides (see Section 8.3.2) but more usually from pyrazinecarbohydrazides with nitrous acid as exemplified here. [Pg.328]
