Reaction Steps
To a solution of 2-amino-3-hydroxypyridine (15.18 g) in N,N-dimethylformamide (150 ml) was added portionwise a 60% dispersion of sodium hydride in mineral oil (6.06 g) with ice-cooling and stirring over a period of 10 minutes. After being stirred at 0°-5° C. for 30 minutes and then at ambient temperature for 1 hour, a solution of 2-chloromethyl-3-methylthiophene (23.9 g) in N,N-dimethylformamide (10 ml) was added dropwise to the reaction mixture. The mixture was stirred at ambient temperature for 20 hours and poured into water. The resulting precipitate was collected by filtration and dissolved in methylene chloride. The solution was treated with activated charcoal and evaporated in vacuo. The residue was crystallized from diethyl ether to give 2-amino-3-(3-methyl-2-thienylmethoxy)pyridine (23.6 g).
