実験手順

A mixture consisting of 9.3 gm of 2-chloro-4,6-dimethyl-nicotinic acid, 5.41 gm of o-phenylenediamine and 25 ml of butyl glycol was heated at 170° C. for 90 minutes while stirring. The mixture was subsequently cooled to 60° C. and poured over ice. After adjusting it to a pH-value of 8 with ammonia, the mixture was suction-filtered, and the filter cake was washed with water and recrystallized from aqueous 70% acetic acid, yielding 53% of theory of the compound named in the heading, which had a melting point of 297°-299° C.
