Reaktionsschritte
3-Amino-4-(methoxylcarbonyl)benzoic acid (2.5 g, 12.8 mmol) was dissolved in a mixture of THF-MeOH—H2O (40 mL, 30:5:5) and then LiOH—H2O (2 g, 64 mmol) was added. The mixture stirred at RT over night. The reaction mixture was concentrated and the residue was dissolved in 5 mL of water and then acidified with 6N HCl to pH˜3. The solid was filtered and dried to give the desired product in 63% yield.
