| 20090005567 | PROCESS FOR THE PREPARATION OF 4-(8-CHLORO-5,6-DIHYDRO-11H-BENZO (5,6)-CYCLOHEPTA-(1,2B) -PYRIDIN-11-YLIDENE)-1-PIPERIDINECARBOXYLIC ACID ETHYL ESTER (LORATADINE) - A process and new oxazolinic intermediates for the preparation of 4-(8-chloro-5,6-dihydro-11H-benzo-[5,6]-clohepta-[1,2-b]-pyridin-11-ylide-ne)-1-piperidinecarboxylic acid ethyl ester (loratadine) is described. The process starts from 2-(4,4-dimethyl-4,5-dihydrooxazol-2-yl)-3-methyl-pyridine, a new intermediate to obtain loratadine. 2-(4,4-dimethyl-4,5-dihydro-oxazol-2-yl)-3-methyl-pyridine is condensed with 3-chloro-benzyl-chloride and the resultant product is treated with Grignard reagent of 4-chloro-N-methyl-piperidine. [3-(2-(3-chloro-phenyl)-ethyl]-pyridin-2-yl-]-1-(methyl-piperidin-4-yl)-methanone is obtained for subsequent hydrolysis. Starting from this last compound it is possible to obtain loratadine with known methods. | 01-01-2009 |
| 20120101281 | PROCESS FOR THE PREPARATION OF DESLORATADINE - The present invention provides a process for the preparation of desloratadine comprising contacting loratadine with a mixture of a weak inorganic base and sodium or potassium hydroxide in a ratio, ranging from 0.01 to 0.15 equivalents of sodium or potassium hydroxide per equivalent of weak inorganic base, in one or more suitable solvents) followed by isolation. | 04-26-2012 |
| 20120184744 | CRYSTALLINE HYDROCHLORIDE SALTS OF C-MET KINASE INHIBITORS - The instant invention relates to crystalline forms of Compound A, an inhibitor of c-MET kinase. Specifically, the instant invention relates to hydrochloride salts of Compound A. | 07-19-2012 |
