  • Patent number: 6316631
    Abstract: This invention relates to a process for converting 2,4-dichloropyridines into 2-aryloxy-4-chloropyridines, comprising reacting a compound of formula (I), wherein R1 is (C1-C4)alkyl; R2 is methyl or ethyl; and R3, R4 and R5 are selected, independently, from (C1-C4)alkyl and (C1-C4)alkoxy; or a pharmaceutically acceptable salt thereof; comprising reacting a compound of formula (II), wherein R1 and R2 are defined as above, with a compound of formula (III), wherein R3, R4 and R5 are defined as above, in the presence of a base that is capable of deprotonating the compound of formula (III), optionally in the presence of an organometallic halide or oxide and a suitable solvent, and then optionally converting the resulting compound of formula (I) into a pharmaceutically acceptable salt of such compound.
