実験手順
Ethyl (3-{5-amino-6-[(methylamino)carbonyl]pyrazin-2-yl}phenyl)carbamate was synthesized according to the procedure described in above from 3-amino-6-(3-aminophenyl)-N-methylpyrazine-2-carboxamide and ethyl chloroformate. Yield 55%: 1H NMR (400 MHz, d6-DMSO): 9.60 (br s, 1H), 8.68 (br s, 2H), 8.12 (br s, 1H), 7.80 (d, 1H), 7.52 (d, 1H), 7.39 (t, 1H), 4.06 (q, 2H), 2.85 (br s, 3H), 1.24 (t, 3H); MS (EI) for C15H17N5O3: 316 (MH+)
