Reaction Conditions:
with water;lithium hydroxide in tetrahydrofuran;methanol;Reflux;
Steps:
General procedure: 3, 4, 5, 6: Hydrolysis of benzoic acidmethyl ester derivative(V, VI, and X) was accomplished by refluxing tetrahydrofuran/methanol (MeOH)/H2O (5:3:2) solution in the presence of lithiumhydroxide. The reaction mixture was acidified by the addition of1 M HCl(aq) then extracted with ethyl acetate and washed withbrine. The organic layer was dried over anhydrous MgSO4, filtered,and the solvent was evaporated to give anthranilic acid derivatives(3, 4, 5, and 6; Supplemental Methods, compound synthesis 1).
