Reaction Steps

Hydroxylamine hydrochloride (10.11 g, 145.5 mmol) was added to a solution of 4-(chloromethyl)benzaldehyde 4 (7.5 g, 48.51 mmol) in EtOH. The mixture was heated at 50° C. for 3 h then concentrated in vacuo. The residue was partitioned between DCM and water. The combined organic extract was dried (MgSO4) and concentrated in vacuo yielding a white solid that was used without further purification (8.1 g, 98%). 1H NMR (400 MHz, DMSO) d 4.77 (2H, s), 7.46 (2H, d, J=8.0 Hz), 7.60 (2H, d, J=8.0 Hz), 8.15 (1H, s), 11.32 (1H, s).
