참여 물질

반응 단계

To a solution of 4-methoxy-2,3-dihydro-1H-inden-1-one (1.0 g, 1.0 eq.) in 25 ml MeOH was added NH2OH.HCl (0.493 g, 1.15 eq.) and sodium acetate (0.597 g, 1.18 eq.). The resulting mixture was stirred at room temperature overnight. The reaction mixture was diluted with 100 ml ice-water. The white precipitate was collected by filtration, washed with 3×20 ml water and dried in vacuo to afford 1.08 g (yield 99%) 4-methoxy-2,3-dihydro-1H-inden-1-one oxime which was used to next step without further purification.
