Versuchsvorschrift

The crude methyl 2-hydroxybenzoate was dissolved in n-propylamine (400 mL). The reaction mixture in a sealed reactor was stirred at 80° C. overnight. The reaction mixture was concentrated under reduced pressure to give the crude material that was purified by silica gel flash column chromatography to afford 120 g (84%) of 2-hydroxy-N-propylbenzamide. LCMS ESI (+) m/z 180 (M+1) detected.
