実験手順

Fuming nitric acid (1.5 ml, 36.2 mmol) was added slowly at 0° C. to a solution of 3-methoxy-4-(3-morpholinopropoxy)benzoic acid (7.78 g, 23.5 mmol) in TFA (25 ml). The cooling bath was removed and the reaction mixture stirred at ambient temperature for 1 hour. The TFA was evaporated and ice was added to the residue. The precipitate was collected by filtration and washed with a minimum of water followed by toluene and ether. The solid was dried under vacuum over phosphorus pentoxide to give 5-methoxy-4-(3-morpholinopropoxy)-2-nitrobenzoic acid trifluoroacetate (7.54 g, 71%yield) which was used without further purification.
