Procedure
To a mixture of 2-aminonicotinic acid (5.3 g, 38 mmol) and 4-chloroaniline (4.9 g, 38 mmol) and DIEA (9 ml, 48 mmol) at 0° C. in CH2Cl2 was added EDC (9.5 g, 48 mmol) and HOBt (5.1 g, 38 mmol), the reaction was warmed to RT and stirred overnight. The solvent was evaporated under reduced pressure and quenched with 2N NaOH solution (60 ml) and stirred for 20 min. The precipitate was filtered to give the titled compound. MS (ES+): 248 (M+H)+; (ES−): 246 (M−H)−.
