Participants

Reaction Steps

2-Amino-5-(1-ethyl-6-oxo-1,6-dihydro-3-pyridinyl)-6-(2-furyl)nicotinic acid (20 mg, 61.5 μmol), 1-hydroxybenzotriazole (28 mg, 183 μmol), 3-(3′-dimethylaminopropyl)-1-ethyl carbodiimide (29 mg, 187 μmol), ammonium chloride (16 mg, 299 μmol), and a suspension of triethylamine (43 μL, 309 μmol) in N,N-dimethylformamide (1.0 mL) was stirred at room temperature for 18 hours. After diluting the reaction solution with water, the resulting solid was collected by filtration and washed with water, to give the title compound (9 mg, 45%) as a pale yellow solid.
