What is this intermediate?
(R)-3-(7-Cyano-5-(2-Aminopropyl)Indolin-1-yl)Propyl Benzoate — also known as 5-[(2R)-2-aminopropyl]-1-[3-(benzoyloxy)propyl]-2,3-dihydro-1H-indole-7-carbonitrile — is the key chiral aminopropyl-indoline building block used in the industrial synthesis of Silodosin. Its free primary amine is condensed with 2-(2-(2,2,2-trifluoroethoxy)phenoxy)ethyl methanesulfonate — another intermediate manufactured by Prudence Lifecare — to build Silodosin's full molecular skeleton, which is then deprotected and hydrolyzed to give the finished API.
