실험 절차

To a solution of quinoxaline-6-carboxylic acid (56.2 mg, 0.318 mmol) in 7 ml DMF were added EDCI (62 mg, 0.32 mmol), TEA (53.9 μl, 0.38 mmol) and HOBt (49.3 mg, 0.36 mmol). After 30 min, a solution of Example 15 (103.4 mg, 0.249 mmol) in 1 ml DMF was added. The reaction mixture was then stirred overnight at RT before evaporation to dryness. The residue was partitioned between DCM (50 ml) and 1N solution of HCl (20 ml). The DCM layer was washed with 10% solution of sodium carbonate (2×20 ml), dried over sodium sulfate, concentrated and purified by reverse phase HPLC (gradient from CH3CN/H2O/TFA: 5/95/0.05 to CH3CN/H2O/TFA: 80/20/0.05) to yield the titled compound (35 mg). Retention time: 2.16 min., 571 (M+1) (LCMS conditions: LC Micromass platform (APCI+, DAD (210-400 nm)), Column: TSK gel Super ODS 4.6 mm ID×5 cm, Flow rate: 2.75 mL/min, Gradient: from 100% eluent A to 100% eluent B in 2 min., with a plateau with 100% eluent B during 1 min. Eluent A: H2O (0.05% TFA), Eluent B: CH3CN/H2O/TFA (80/20/0.05)).
