A solution of methoxyphthalic acid obtained as per Example 5 (0.1 mol) in 100 ml methanol was added with CuCl (0.1 mol) and HCl (0.1 mol). The solution was heated to reflux for 30 min. The clear solution obtained was evaporated to dryness under reduced pressure. The residue obtained was dissolved in a 1:3 water-methanol mixture and acidified. The product was separated by cooling, collected by filtration and air dried. The product yield was 63-66%.
