実験手順
To a mixture of 4-chloroanaline (594 mg, 4.7 mmol, 1. eq.), EDC (1.62 g, 8.5 mmol, 2 eq.), HOBT (572 mg, 4.2 mmol, 1 eq.), and DIEA (1.1 ml, 6.3 mmol, 1.5 eq.) in CH2Cl2 (50 ml) was added 5-bromo-2-chloronicotinic acid from Step B (1.0 g, 4.2 mmol). The reaction was stirred at RT overnight. The solution was quenched with water and the organic layer was purified by chromatography (50% EtOAc in hexane) to afford a light-yellow compound. MS (ES+): 347.0, 349.0 (M+H)+; (ES−): 345.0, 347.0 (M−H)−.
