Versuchsvorschrift
2′-Methoxy-5-nitro-biphenyl-3-carboxylic acid (8.62 g, 31.5 mmol) was added to a mixture of MeOH (89 mL) and conc. aqueous HCl (4.9 mL). The reaction mixture was stirred at 80° C. for 24 hours, and then stirred for 18 hours at room temperature. The reaction mixture was filtered, and the resulting solid was washed with MeOH and dried to give 8.2 g of 2′-methoxy-5-nitro-biphenyl-3-carboxylic acid methyl ester, MS (M+H)=288.
