Participants

Reaction Steps

6-Chloronicotinic acid (157.5 mg, 1 mmol) and 8 ml of DMF were stirred at room temperature while 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (384 mg, 2 mmol), hydroxybenzotriazole (162 mg, 1.2 mmol), triethylamine (404 mg, 4 mmol) and 4-methoxy-o-phenylenediamine (166 mg, 1.2 mmol) were added. The mixture was stirred for 20 hours at room temperature. The mixture was diluted with 400 mL of brine and extracted with 200 ml of ethyl acetate. The ethyl acetate was removed under vacuum. To the residue was added 5 ml of absolute ethanol. The solids were collected by vacuum filtration, washed with absolute ethanol and dried under vacuum to give the title compound (144 mg, 52% yield) as a brown solid. LC-MS (m/z) 278 (M+1).
