Procedure

Dimethyl 2-aminoterephthalate (10.45 g), 2,4-dichlorobenzyl chloride (11.74 g), potassium iodide (8.33 g) and potassium carbonate (13.82 g) in a mixed solvent of toluene (50 ml) and water (30 ml) were heated under reflux for 20 hr. After cooling, toluene (50 ml) was added and the precipitated yellow crystals were collected by filtration. The crystals were washed with water and toluene and dried to give the objective compound (7.87 g). The mother liquor was concentrated and crystallized from ethyl acetate to give the second crystals (4.43 g).
