METHOD FOR PREPARING (3-CHLORO-4-FLUOROPHENYL)-(4-FLUORO-4-{[(5METHYL-PYRIMIDIN-2-YLMETHYL)-AMINO]-METHYL}-PIPERIDIN-1-YL)-METHANONE AND NOVEL INTERMEDIATE PYRIMIDINE DERIVATIVES

摘要

The present invention concerns the method for preparing (3-chloro-4-fluorophenyl)-(4-fluoro-4-{[(5-methyl-pyrimidin-2- ylmethyl)-amino]-methyl}-piperidin-1-yl)-methanone of formula (II) by condensation between 5-methyl-pyrimidin-2-methylamine of formula (I) and cyanohydrin of formula (III).
