Bupranolol is an antagonist at the cardiostimulatory low-affinity state of b(1)-adrenoceptors and is known to treat hypertension and tachycardia.

ChEBI: Bupranolol is an aromatic ether.

A mixture of 16.3 g of (2-chloro-5-methylphenyl)glycidic ether (from epichlorohydrin and 2-chloro-5-methylphenol) and 6.2 g of t-butylamine in 50 ml of ethanol is heated at reflux for 6 hours. The solvent is removed, the residue is washed with water and then extracted with benzene. The dried extract is evaporated to give 1-t-butylamino-3-(2-chloro-5-methylphenoxy)-2- propanol. Treatment of the free base in benzene solution with dry hydrogen chloride yields the hydrochloride salt.
