Reaction Steps

69 g (0.26 mol) of methyl 1-hydroxy-2-naphthylglyoxylate and 44 g (0.53 mol) of O-methylhydroxylamine hydrochloride in 800 ml of methanol are stirred under reflux for 6 h. The mixture is then concentrated; the residue is taken up in ethyl acetate, and the solution is washed with H2O, dried over sodium sulfate and concentrated again. 52 g (0.20 mol) of methyl 1-hydroxy-2-naphthylglyoxylate O-methyloxime (77% yield) are obtained.
