Participants

Reaction Steps

In a mixture of 3 g of 5-methylanthranilic acid in 30 ml of chloroform is dissolved 3 ml of triethylamine, to this mixture is added a solution of 4.2 g of 3,4-dimethoxycinnamoylchloride in chloroform under cooling. The mixture is stirred at room temperature for 2 hours and then heated under reflux for 2 hours. The reaction mixture is concentrated under a reduced pressure, to the residue is added water and hydrochloric acid is added to make the mixture the weakly acidic. The precipitated crystals are collected by filtration recrystallized from ethanol to obtain 4.8 g of N-(3,4-dimethoxycinnamoyl)-5-methylanthranilic acid as pale yellow needles.
