Reaction Steps

To a solution of 5-hydroxypyridine-2-carboxylic acid (0.103 g, 0.74 mmol) in dichloromethane was added diisopropylethylamine (0.279 mL, 1.6 mmol), followed by 1-hydroxybenzotriazole monohydrate (0.012 g, 0.8 mmol) and EDCI (0.153 g, 0.8 mmol). The resulting mixture was stirred for 15 minutes and 3-phenyl-1-propylamine (0.108 g, 0.8 mmol) was added. After stirring for 22 h, the reaction mixture was diluted with dichloromethane (80 mL), washed with water, dried over anhydrous Na2SO4 and concentrated in vacuo. Purification by column chromatography afforded 5-hydroxypyridine-2-carboxylic acid (3-phenylpropyl)amide as white crystals (0.116 g, 61% yield). MS (ES+) m/z 257.2 (M+1).
