To a solution of 4- hydroxyphthalic acid (20 g, 110 mmol) in CH3OH (100 mL) was added SOC12 (20 mL), The resulting solution was stirred at 80 °C for 4 hrs, The volatile was removed in vacuo to yield compound C1-2 as a white solid (23 g, yield: 99percent), which was used directly in the next step without further purification. ‘H NMR (CDCI3, 400 MHz) : 7.77(d, J = 8.8 Hz, lH), 7.03 (d, J 2 Hz, lH), 6.95 (dd, J 8.4 and 2.0 Hz, 1H), 3.93 (s, 3H), 3.88 (s, 3H); MS (ESI): ,n/z 21 l(M÷l).
92% at 0℃; for 20 h; A solution of 4-hydroxyphthalic acid 1 (25.0 g, 137 mmol) in MeOH (700 mL) was charged with SOCl2 (30.0 mL, 412 mmol) at 0° C. and stirred at room temperature for 20 h.
The solvent was removed and the residue was partitioned between saturated aqueous NaHCO3 solution (100 mL) and CH2Cl2 (250 mL).
The CH2Cl2 layer was separated and the aqueous layer was extracted with CH2Cl2 (2*250 mL).
The combined organic extracts were washed with brine, dried over Na2SO4, and concentrated to afford compound 2 (26.5 g, 92percent) as a colorless oil: 1H NMR (400 MHz, CDCl3) δ 7.72 (d, J=8.5 Hz, 1H), 7.00 (d, J=2.6 Hz, 1H), 6.91 (dd, J=8.5, 2.6 Hz, 1H), 3.89 (s, 3H), 3.85 (s, 3H).
90% Heating / reflux A solution of 5 g (27.6 mmol) of 4-aminophthalic acid in 50 ml of 1M sulphuric acid is cooled to 0° C. and a solution of 2.27 g of sodium nitrite in 6 ml of water is then slowly added. After 15 minutes at 0° C., 15 ml of concentrated sulphuric acid are added and the mixture is heated at 100° C., with vigorous stirring, for 1 hour. At room temperature, the reaction medium is extracted with ethyl acetate and washed with water. After decantation, the organic phase is dried over magnesium sulphate and concentrated. The residue is purified on a silica column (dichloromethane 80-methanol 20). It is then dissolved in 100 ml of methanol and refluxed with 2 ml of acetic acid. After the disappearance of the diacid, the methanol is evaporated and the product is taken up in ethyl acetate and washed with water. [00350] M=5.2 g.

87% With hydrogenchloride In isopropyl alcohol at 0℃; for 24 h; Reflux A solution of 4-hydroxyphthalic acid 16 (25.0 g, 137 mmol) in MeOH (500 mL) was charged with 6 N HCl in z'-PrOH (46.0 mL, 274 mmol) at 0 °C and refluxed for 24 h. The solvent was removed and the residue was partitioned between saturated aqueous NaHCC solution (100 mL) and EtOAc (250 mL). The EtOAc layer was separated and the aqueous layer was extracted with EtOAc (2 χ 250 mL). The combined organic extracts were washed with brine, dried over Na2S04, and concentrated to afford compound 17 (25.0 g, 87percent) as a brown color solid: NMR (400 MHz, (Χ,) δ 7.72 id, ./ 8.5 Hz, 1 H), 7.00 (d, J = 2.6 Hz, H I ), 6.91 (dd, J = 8.5, 2.6 Hz, 1H), 3.89 (s, 3H), 3.85 (s, 3H).
55% at 10 - 70℃; 4-hydroxyphthalic acid (50g, 274.5mmol) was dissolved in methanol (800mL) and cooled to 10°C. Sulfuric acid (134g, 1.37mol) was slowly added dropwise with stirring. After the addition was complete the reaction temperature was raised to 70°C overnight. Cooling to room temperature, it was concentrated in vacuo. It was extracted with ethyl acetate (700mL) and washed with water (500mL × 3). The organic phase was dried over anhydrous sodium sulfate and concentrated in vacuo to give the product (32g, 55percent yield).
