Reference of 84163-77-9, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 84163-77-9, name is 6-Fluoro-3-(4-piperidinyl)-1,2-benzisoxazole. In an article£¬Which mentioned a new discovery about 84163-77-9
PROCESS FOR PREPARING PALIPERIDONE AND PHARMACEUTICALLY ACCEPTABLE SALTS THEREOF
The present invention discloses the process for the preparation of paliperidone and its pharmaceutically acceptable salts comprising (a) condensing 2-amino-3-hydroxy- pyridine with 2-acetylbutyro lactone in the presence of an acid catalyst to isolate 9- hydroxy-3-(2-hydroxyethyl)-2-rnethyl-4H-pyrido[l, 2-a] pyrimidin-4-one; treating 9- hydroxy-3-(2-hydroxyethyl)-2-methyl-4H-pyrido[l, 2-a] pyrimidin-4-one with a chlorinating agent; hydrogenating the product in the presence of one or more lewis acids to obtain 3-(2-chloroethyl)-6,7,8,9-tetrahydro-9-hydroxy-2-methyl-4H-pyrrido[l,2-a]- pyrimidin-4-one; and condensing3-(2-chloroethyl)-6,7,8,9-tetrahydro-9-hydroxy-2- methyl-4H-pyrrido[l,2-a]-pyrimidin-4-one. The present invention also discloses processes for the preparation of intermediates useful in the preparation of paliperidone and its pharmaceutically acceptable salts.
