Reaktionsschritte

To a solution of 2-chloro-4-nitrobenzoic acid (10 g, 0.06 mol) in MeOH (120 mL) was added H2SO4 (5 mL). The resulting mixture was stirred at 60° C. overnight. After cooling to room temperature, the mixture was brought to pH=8 using sodium bicarbonate solution. After removal of MeOH, the resulting crude mixture was purified by column chromatography (20% CH2Cl2/PE) to afford 4 g of the title compound. LC-MS: m/z 216.6 (M+H)+
