A mixture of 4-methoxybenzyl bromide (25 g, 0.159 mol) and 2-amino-3-hydroxypyridine (15.9 g, 0.145 mol) in 40% aqueous sodium hydroxide solution (150 ml) and dichloromethane (150 ml) was treated with Adogen 464 (5 ml) and stirred vigorously at room temperature for 16 hours. The mixture was diluted with further water and dichloromethane, the product extracted into dichloromethane, and the combined organic layers washed with water, dried and evaporated. The resulting solid was washed with ether to yield the product (25.6 g, 70%)
