실험 절차

To a stirred solution of methanesulfonamide (0.026 g, 0.268 mmol) and triethylamine (0.030 mL, 0.229 mmol) in toluene (2 mL) was added trimethylsilyl chloride (0.020 mL, 0.152 mmol). The mixture was stirred at 90° C. for 1 hr, and then concentrated under reduced pressure. To the residue diluted with dichloromethane (2 mL) were added triethylamine (0.020 mL, 0.152 mmol), 4,4-dimethylaminopyridine (0.002 g, 0.015 mmol), benzotriazole-1-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate (0.040 g, 0.091 mmol) and 5-[1-(tert-butoxycarbonyl)-3-piperidinyl]-7-{2-(cyclopropylmethoxy)-6-[(4-methoxybenzyl)oxy]phenyl}-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylic acid (0.050 g, 0.076 mmol) successively. The mixture was stirred at room temperature for 6 hrs. The mixture was extracted with ethyl acetate and water. The separated organic phase was washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. The resulting residue was purified by preparative TLC (hexane/ethyl acetate=1/1×2) to give tert-butyl 3-(2-{2-(cyclopropylmethoxy)-6-[(4-methoxybenzyl)oxy]phenyl}-6-{[(methylsulfonyl)amino]carbonyl}-7-oxo-7,8-dihydro-1,8-naphthyridin-4-yl)-1-piperidinecarboxylate (0.024 g, yield; 43%).
