Reaction Steps

To a stirred solution of methyl 1,1-dimethyl-3-oxo-2,3-dihydro-1H-indene-5-carboxylate (430 mg, 1.97 mmol, 1.0 eq.) in methanol (7.5 ml) was added hydroxylamine hydrochloride (340 mg, 4.93 mmol, 2.5 eq.) followed by sodium acetate (807 mg, 9.85 mmol, 5.0 eq.) and the reaction mixture was heated at reflux for 2 h at 80° C. The reaction mixture was concentrated and then extracted with ethyl acetate (3×40 ml). The organic part was separated, washed with water (20 ml) and brine (20 ml) and dried over sodium sulfate. After concentrating the filtrate the crude product thus obtained was directly taken through to the next step without purification.
