| titleOfInvention | An improved process for the synthesis of (±)2-amino-n-(2,(2,5-dimethoxyphenyl)-2-hydroxyethyl) acetamide monohydrochloride |
| abstract | This invention relates to an improved process for synthesizing (.plusmn.) 2-Amino-N-[2,(S,5-dimethoxyphenyl)-2-hydroxyethyl] acetamide monohydrochloride in good yield and in a cost effective manner from 1-(2,5dimethoxyphenyl)-2-bromoethanone by reacting the same with hexamine in the presence of novel solvent system comprising Tetrahydrofuran and water. The resulting aminoethanone is acylated with haloacetylchloride and sodium acetate in acetone-water solvent system. This product is reduced selectively first with sodium borohydride and subsequently with stannous chloride. This product is converted in situ to the corresponding hydrochloride salt immediately after reduction on its own. |
