実験手順

2.5 ml pyridine is added to a suspension of 0.25 mol salicylamide in 50 ml xylene. While boiling under reflux (water separator) 0.26 mol 4-methoxybenzoyl chloride is added within 3 hours and it is heated to boiling for a further 3 hours under reflux. A further 2.5 ml pyridine is added and it is heated for a further 8 hours. After cooling to room temperature it is poured onto 400 ml isopropanol and suction filtered. The residue is recrystallized from ethylene glycol monomethyl ether.
