Abstract
There is disclosed an improved process for preparing albuterol which comprises reacting a 5-(haloacetyl)-2-hydroxybenzaldehyde with 1,1-dimethylethanamine in an organic solvent and in an inert atmosphere to form 5-[[(1,1-dimethylethyl)amino]acetyl]-2-hydroxybenzaldehyde and reducing the carbonyl functions to the corresponding hydroxy groups to form albuterol.
