실험 절차

10-methoxy-5H-dibenz(b,f)azepine (29.9 g, 0.134 mol) was added to 300 ml acetonitrile in a three-neck flask (500 ml) equipped with a mechanical stirring apparatus. The mixture was stirred at room temperature for 15 minutes, and then NaOCN (18 g, 0.277 mol) was added, followed by pyridinium p-toluenesulfonate (75 g, 0.3 mol). The mixture was stirred at room temperature for about 4 hours, at which time TLC indicated that the reaction was complete (disappearance of 10-methoxy-5H-dibenz(b,f)azepine). 30 ml water was added, and the mixture stirred for 15 minutes. The solids were filtered and the filtrate was concentrated under vacuum. The semi-solid residue was triturated with acetone to provide a creamy solid, which was dried at 80° C. to provide 18 g (0.068 mol, 50% yield) of 10-methoxy-5H-dibenz[b,f]azepine-5-carboxamide (10-methoxycarbamazepine).
