Hydroxylamine → 7-Methoxy-1-tetralone Oxime

Participants

Reaction Steps

To a solution of 7-methoxytetralone (15 g) in MeOH (175 mL), NH2OH (50% in H2O, 15.7 mL) and AcOH (4 mL) was added. After stirring for 1 hour, the solution was concentrated until a solid began to appear. The reaction was poured into dilute aqueous NaHCO3 (500 mL), and the resulting solid was filtered to provide the title compound (17.8 g): 1H NMR (DMSO-d6) δ 11.08 (s, 1H), 7.35 (s, 1H), 7.08 (d, 1H), 6.84 (d, 1H), 3.71 (s, 3H), 2.62-2.49 (m, 4H), 1.77-1.64 (m, 2H).
