somewhat of a more prolonged action. It is recommended for use as an inhaled drug for
treating bronchial asthma.
Chemical Properties
Off-White Solid
Uses

Definition
ChEBI: 8-hydroxy-5-[1-hydroxy-2-(propan-2-ylamino)butyl]-1H-quinolin-2-one is a member of quinolines.
brand name
Pro-Air (Parke-Davis).
Synthesis
Procaterol, 5-[1-hydroxy-2-[(1-methylethyl)amino]butyl]-8-hydroxy-2-(1H)
quinolone (23.3.25), is synthesized by acylation of 8-hydroxy-2(1H)-quinolone with 2-bromobutyric acid chloride at the fifth position of the quinoline system, which gives the
compound 23.3.23. This undergoes action of isopropylamine, forming an aminoketone
23.3.24, the carbonyl group of which is reduced by sodium borohydride, giving procaterol
(23.3.25) .
