- Preparation of 2-chloro-5-methyl-pyridine
-
A process for the preparation of 2-chloro-5-methylpyridine of the formula STR1 which comprises reacting 3-methyl-pyridine-1-oxide of the formula STR2 with a chlorinating agent of the formula STR3 in which R1 represents alkyl, halogenoalkyl, cycloalkyl, optionally substituted aryl, NR2 R3 or OR4 in which R2 and R3 individually represent alkyl, cycloalkyl or aryl or together represent alkanediyl or oxaalkanediyl and R4 represents alkyl, cycloalkyl or optionally substituted aryl, in the presence of a basic organic nitrogen compound and in the presence of a diluent at a temperature between about -20° C. and +150° C.
