There is disclosed an improved process for preparing albuterol which comprises reacting a 5-(haloacetyl)-2-hydroxybenzaldehyde with l,l-dimethylethanamine in an organic solvent and in an inert atmosphere to form 5-[[(l,l-dimethylethyl)amino]acetyl]-2-hydroxybenzaldehyde and reducing the carbonyl functions of this last-named compound to the corresponding hydroxy groups to form albuterol.
本发明公开了一种制备阿布特罗的改进工艺,该工艺包括在有机溶剂和惰性气氛中,使 5-(卤乙酰基)-2-羟基
苯甲醛与 l,l-二甲基
乙胺反应,生成 5-[[(l,l-二甲基乙基)
氨基]乙酰基]-2-羟基
苯甲醛,然后将该化合物的羰基官能团还原成相应的羟基,形成阿布特罗。
