실험 절차
A solution of 3,8-difluoro-4-hydroxy-4-(hydroxymethyl)-4,5-dihydro-7H-pyrrolo[3,2,1-de]-1,5-naphthyridin-7-one (710 mg, 2.79 mmol) in dichloromethane (35 ml) and tetrahydrofuran (35 ml) was treated with triethylamine (0.58 ml, 4.19 mmol), para-toluenesulphonyl chloride (586 mg, 3.07 mmol) and dibutyltin oxide (35 mg, 0.14 mmol). After 6 hours stirring at room temperature under argon, the mixture was evaporated and water (200 ml) was added. The aqueous phase was extracted with dichloromethane (3×200 ml) and the combined organic extracts dried over magnesium sulphate and evaporated to give the desired compound (1.2 g, 100%) which was used without further purification.
