実験手順
To a solution of 0.46 gram (2.85 mmole) 6-amino-3,4-dihydro-2H-naphthalen-1-one in 25 mL pyridine was added 0.605 grams (3.42 mmoles) benzenesulfonyl chloride. The reaction mixture was stirred at 23° C. for 24 hours. The mixture was diluted with 100 mL water and extracted with 200 mL ethyl acetate. The organic phase was dried (magnesium sulfate) and concentrated under reduced pressure. The residue was subjected to low pressure column chromatography over silica gel 230-400 mesh eluting with 50% ethyl acetate in hexane. The title compound was obtained as a solid, 0.48 gram (56%), m.p. 164-165° C., M−H=300.
