Reaction Steps

2-Aminomethylpyridine (4.0 g, 37 mmol) and phthalic anhydride (5.5 g, 37 mmol) were dissolved in toluene (100 ml), and triethylamine (3.7 g, 36 mmol) was added thereto. The mixture was refluxed for 3 hrs. The solvent was evaporated, and the residue was recrystallized from hexane-ethanol to give the titled compound (7.6 g, 86%).
