Process for preparing amlodipine benzenesulphonate |
| abstract |
The invention relates to a novel process for preparation of amlodipine benzenesulphonate of formula (I) by reacting a new 2-[/2-N-(2-carboxy-benzoyl)-aminoethoxy/methyl/]-4-(2-chlorophenyl)-3-ethoxycarbonyl-5-methoxycarbonyl-6-methyl-1,4-dihydropyridine derivative of general formula (II) wherein X represents hydrogen or alkali metal or alkali earth metal or quaternary ammonium - with benzenesulphonic acid. |
