Reaction Steps

5-Bromo-1-indanone and O-methylhydroxylamine hydrochloride were combined in pyridine and stirred at ambient temperature for 16 hours. The mixture was concentrated under reduced pressure and the residue was suspended in diethyl ether. The suspension was filtered and the filter cake was washed with diethyl ether. The filtrate was washed with water, 1N HCl, water, and concentrated to provide the title compound. 1H NMR (300 MHz, d6-DMSO) 7.63 (m, 2H), 7.48 (m, 2H), 3.90 (s, 3H), 3.00 (m, 2H), 2.80 (m, 2H); MS (DCI/NH3) m/e 240 (M+H)+.
