実験手順
A mixture of 1-(p-methoxyphenyl)-4-piperidinone (prepared following the procedure reported in: Scherer, T. et al., Recl. Trav. Chim. Pays-Bas (1993), 112(10), 535-48.) (5.13 g, 25 mmol), K2CO3 (6.22 g, 45 mmol), hydroxylamine hydrochloride (2.606 g, 37.5 mmol) and ethanol was refluxed for 20 min. After cooling H2O (50 ml) was added and white crystals of 1-(4-methoxy-phenyl)-piperidin-4-one oxime (4.56 g, 83%, Mp. 116-119°, MS: m/e=220 (M+)) was collected.
