Abstract
The title compd. is obtainable from 1,3-dicyclohexylcarbodiimide and pyrazine-2-carboxylic acid in DMF in the presence of catalytic amts. of [H3Ru4(C6H6)4OH]Cl2. Crystals of the compd. are orthorhombic, space group P212121, with a 9.4745(8), b 11.9101(7), c 15.8212(10) Å; Z = 4, dc = 1.229; R = 0.028, Rw(F2) = 0.058 for 3477 reflections. The intermol. N-H...O=C H bond is responsible for the formation of infinite chains stretching along the a axis of the crystal. [on SciFinder(R)]
