Method of Preparation of (R)-(-)-5(2-Aminopropyl)-2-Methoxybenzenesulfonamide |
| abstract |
A method of preparation of (R)-(−)-5-(2-aminopropyl)-2-methoxybenzenesulfonamide of formula I and its use for production tamsulosin. A protective group is introduced to N-[(1R)-2(4-methoxyphenyl)-1-methylethyl]-N-[(1R)-1-phenylethyl)]amine and the resulting amide of formula IX is chlorosulfonated and the resulting sulfochloride is converted to a sulfonamide of formula X, from which the compound of formula I is obtained by hydrogenation. |
