With triethylamine In propan-1-ol at 70℃; for 8h; | 88 First step, hydroxyamine hydrochloride (619 mg) and NaOAc (1.47 g) were added to a solution of 1-(4-methoxyphenyl)-butanone (800 mg) in EtOH (80 ml). The reaction mixture was stirred at 60°C for 6 h. EtOH was removed under reduced pressure. H2O (40 ml) was added to the residue, and the resulting solution was extracted with EtOAc (3 × 40 ml). The EtOAc of the combined organic layer was removed by rotary evaporation under reduced pressure to yield 1-(4-methoxyphenyl)-butanone oxime (870 mg) as a pale yellowish solid. Second step, a mixture of 1-(4-methoxyphenyl)-butanone oxime (870 mg) and concentrated HCl (2.38 ml) in EtOH (50 ml) was subjected to hydrogenation at atmospheric pressure in the presence of 10% Pd/C (90 mg). The reaction solution was filtered and the filtrate was concentrated. The residue was suspended in EtOAc, and the suspension was filtered to yield 1-(4-methoxyphenyl)-butylamine hydrochloride (965 mg) as a white solid.
