실험 절차
14.25 g (0.1 mol) of 2-chloro-5-aminomethylpyridine and 11.1 g (0.11 mol) of triethylamine are dissolved in 150 ml of methylene chloride. 14.8 g (0.105 mol) of benzoyl chloride are then added dropwise at about 20° C. and the reaction mixture is subsequently stirred overnight at room temperature. It is washed three times with water and the organic phase is dried and concentrated. 24.6 g (99.8% of theory) of 2-chloro-5-benzoylaminopyridine are obtained as white crystals of melting point 118°-120° C.
