実験手順
A mixture of 7-amino-4-(2-fluorophenyl)-9H-pyrido[3,4-b]indole-1-carboxamide (25 mg, 0.078 mmol), isonicotinic acid (11.53 mg, 0.094 mmol), BOP (49.7 mg, 0.112 mmol), and N-methylmorpholine (0.037 mL, 0.337 mmol) in DMF (0.25 mL) was stirred at room temperature for 1.5 hr. The mixture was diluted with MeOH (1.5 mL) and subjected to prep LC. reverse phase HPLC purification. The correct fraction was concentrated under vacuum, basified with saturated NaHCO3 solution to pH 9. The precipitating product (10.8 mg, 0.025 mmol, 32.5% yield) was collected as a pale solid by suction filtration. LCMS (M+H)+=426.14. 1H NMR (500 MHz, DMSO-d6) δ: 11.95 (s, 1H), 10.96 (s, 1H), 6.80 (m, 2H), 8.44 (s, 1H), 8.33 (s, 1H), 8.27 (s, 1H), 7.89 (m, 2H), 7.79 (s, 1H), 7.71-7.67 (m, 2H), 7.54-7.48 (m, 2H), 7.42 (dd, J1=8.6 Hz, J2=1.9 Hz, 1H), 7.28 (d, J=8.6 Hz, 1H).
