Participants

Reaction Steps

A mixture of 4-(4-methoxybutan-2-yl)benzoic acid (177 mg, 0.85 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (245 mg, 1.3 mmol), N-hydroxybenzotriazole (176 mg, 1.3 mmol) and triethylamine (258 mg, 2.55 mmol) in dichloromethane (50 mL) was stirred for 30 minutes at room temperature. Then to the mixture, 3-(aminomethyl)-4,6-dimethylpyridin-2-ol (130 mg, 0.85 mmol) was added. The resultant mixture was stirred at room temperature for 12 hours. Then the mixture was washed with water (30 mL×3). The organic layer was concentrated to give a residue and the residue was purified by column chromatography (silica gel, dichloromethane/methanol=20:1) to give N-((2-hydroxy-4,6-dimethylpyridin-3-yl)methyl)-4-(4-hydroxybutan-2-yl)benzamide (47 mg, 17%). LRMS (M+H+) m/z: calcd 324.19 found 324. 1H.
