Procedure

1-(3,4-dichlorobenzamido)pyridinium internal salt (20 parts) and dimethyl sulphate (100 parts) were heated together at 100° C. for four hours. On cooling, crystals separated which were filtered off, washed and dried to give 1-(3,4-dichloro-N-methylbenzamido)pyridinium methyl sulphate (15 parts), melting point 135° C.
