FeCl3. promoted condensation of hydroxyiminoketones with aminoacetonitriles followed by catalytic hydrogenation afforded the desired pyrazines in moderate-good yields. This protocol provides an efficient and practical synthesis of substituted 2-aminopyrazines. (C) 2002 Elsevier Science Ltd. All rights reserved.
