Procedure

1-Aminopyridinium chloride (104 parts) and p-chlorobenzoyl chloride (150 parts) were heated in xylene (750 parts) at 140° C for 4 hours. The solid product was filtered off and recrystallised from n-butanol to give 1-(p-chlorobenzamido)pyridinium chloride (209 parts, 97% yield), melting point 241° C.
