Reaction Steps

To a mixture of 2-chloronicotinic acid (4 g) and 4-chloroanaline (3.2 g) and DIEA (6 ml) in CH2Cl2 (200 ml) was added EDC (6 g) and HOBt (3.3 g). The reaction was stirred at RT overnight and washed with 2 N NaOH (100 ml), H2O (150 ml) and brine (100 ml). The organic layer was dried over Na2SO4 and evaporated to give (2-chloro(3-pyridyl))-N-(4-chlorophenyl)carboxamide.
