Reaction Steps
5.87 g of 4-methoxyphenol were dissolved in 8 ml of methanol; 2.61 g of KOH were added, the whole was stirred for 2 hours, and the solvent was evaporated. The solid obtained was dissolved in 150 ml of anhydrous toluene. With stirring, 5 g of 2-chloro-3-nitropyridine were added at 70°-80° C. in the course of 4 hours under a nitrogen atmosphere. The whole was then stirred at ambient temperature for 2 hours. It was washed with 10% aqueous NaOH and then with plenty of water. The organic phase was treated with active carbon at room temperature for 60 minutes. It was filtered and the filtrate was dried with anhydrous magnesium sulphate. After evaporation of the solvent at low pressure, 7.4 g of 3-amino-2-(4-methoxyphenoxy)pyridine (95% yield) were obtained as a pale yellow solid which melted at 105°-107° C. with decomposition.
