Reaction Steps
In a mixture of 20 ml of tetrahydrofuran and 1.6 g of dimethylaniline is dissolved 1.6 g of 4-fluoroanthranilic acid. To this solution is added slowly a solution of 2.3 g of 3,4,5-trimethoxybenzoylchloride in tetrahydrofuran under room temperature and the mixture is strred at room temperature for 5 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 and recrystallized from methanol to obtain 2.1 g of N-(3,4,5-trimethoxybenzoyl)-4-fluoroanthranilic acid as colorless needles.
