Triethylamine → N-[(6-bromopyridin-2-yl)methyl]-2-cyanoacetamide

Participants

Reaction Steps

6-Bromo-2-pyridinemethanamine hydrochloride (0.25 g, 1.12 mmol) was taken up in DMF (8.4 mL) and triethylamine (0.31 mL, 2.24 mmol) was added. After five minutes, cyanoacetic acid (0.095 g, 1.12 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.21 g, 1.12 mmol), 1-hydroxybenzotriazole hydrate (0.18 g, 1.14 mmol) were added and the reaction was maintained at room temperature overnight. Upon completion the mixture was diluted with ethyl acetate, washed with water, dried over magnesium sulfate, filtered and concentrated. The crude material was purified by silica gel chromatography to yield the title compound.
