実験手順

A mixture of 5-(6-fluoro-2-methyl-3-((1-methylcyclopropyl)amino)quinoxalin-5-yl)-2-methyl-1H-pyrrole-3-carboxylic acid (417c) (0.119 g, 0.336 mmol), 0-(˜7-azabenzotriazol-1-yl)-n,′n,′n,′n′-tetramethyluronium-hexafluorophosphate (GenScript Corporation, 0.160 g, 0.420 mmol), DIPEA (0.146 mL, 0.839 mmol), in DMF (1.679 mL) was stirred at RT for 5 min before addition of ammonia (2.0 M solution in MeOH, Sigma Aldrich, 0.336 mL, 0.672 mmol). The resulting mixture was stirred at RT overnight. Reaction mixture was diluted with DCM and washed with water and brine to remove DMF. Purification by Biotage (0-100% EtOAc/hexanes then 30-100% EtOAc:EtOH(3:1)/hexanes) produced desired product. The residue was diluted with DCM and re-washed two times with alternating water and brine washes to remove DMF and provide 5-(6-fluoro-2-methyl-3-((1-methylcyclopropyl)amino)quinoxalin-5-yl)-2-methyl-1H-pyrrole-3-carboxamide (0.031 g, 0.88 mmol, 26% yield). 1H NMR (300 MHz, MeOH) δ ppm 0.84-0.94 (m, 4H) 1.56 (s, 3H) 2.38 (s, 3H) 2.55 (s, 3H) 7.01-7.17 (m, 2H) 7.25-7.35 (m, 1H) 7.37-7.47 (m, 1H) 12.84-13.00 (m, 1H). m/z (ESI, +ve) 354.0 (M+H).
