The Uses of Bopindolol

Bopindolol is an ester prodrug of Pindolol (P468000). Bopindolol is a long acting β-adrenoceptor blocking agent. Bopindolol displays antispasmogenic activity mediated by α1-adrenoceptors and 5-HT2 receptors.

Definition

ChEBI: 1-(tert-butylamino)-3-[(2-methyl-1H-indol-4-yl)oxy]propan-2-yl benzoate is a methylindole that is 2-methyl-1H-indol-4-ol in which the hydrogen of the hydroxy group is replaced by a 2-(benzoyloxy)-3-(tert-butylamino)propyl group. It is a methylindole, a secondary amino compound, an aromatic ether and a benzoate ester.

Manufacturing Process

4-(2-Benzoyloxy-3-t-butylaminopropoxy)-2-methyl-indole:
26 g of benzoic acid are dissolved, while heating, in 50 ml of hexamethylphosphoric acid triamide and 3.5 g of 1-t-butylamino-3-(2-methylindole- 4-yloxy)-2-propanol are added. After cooling, 3.0 g of benzoic acid anhydride are added and stirred for 20 hours at room temperature. The resulting clear, yellow solution is poured onto ice 0.5 liters of ether are added and stirred for 2 hours. After making the liquid alkaline with concentrated ammonia, the ether phase is separated, shaken out with tartaric acid, made alkaline with caustic soda solution while cooling with ice and extracted with methylene chloride. After evaporating the solvent, the residue is crystallized with 1 mol of fumaric acid from methanol and acetone.
