实验步骤: To a mixture of 1-Bromomethyl-2-fluoro-4-methoxy-benzene (4.5 g, 21 mmol) and Tetrabutylammonium iodide (0.66 g, 2.1 mmol) in CH2Cl2 (50 mL) was added a solution potassium cyanide (4.0 g, 60 mmol) in water (50 mL). The resulting biphasic mixture was stirred vigorously for 8 hours. The reaction was poured into water (100 mL) and extracted with CH2Cl2 (2×50 mL). The organics were washed with water (100 mL) and brine (100 mL), dried over Na2SO4, filtered and concentrated. The residue was purified by flash column chromatography (10–30% EtOAc in hexanes) to give the product (2.6 g, 75% yield) as a clear oil. 1H NMR (300 MHz, CDCl3) δ: 3.66 (s, 2 H), 3.82 (s, 3 H), 6.69 (m, 2 H), 7.31 (m, 1 H). extracted with CH2Cl2 (2×50 mL) The organics were washed with water (100 mL) and brine (100 mL) dried over Na2SO4 filtered concentrated The residue was purified by flash column chromatography (10–30% EtOAc in hexanes)

实验步骤: A mixture of 2-amino-3-hydroxy pyridine (1.45g, 0.013 mol), dichloromethane (10 ml) and 40% aqueous sodium hydroxide solution (10 ml) was stirred for five minutes, then 2-fluoro-4-methoxybenzyl bromide (2.9 g, 0.013 mol) and Adogen 464 (1.5 ml) were added and stirring continued for 16 hours. The mixture was diluted with water and extracted with dichloromethane. Drying and evaporation of the organic extracts, and trituration with ether gave the desired product. Yield 1.11 g (34%), m.p. 135°-138 ° C. stirring continued for 16 hours extracted with dichloromethane Drying evaporation of the organic extracts, and trituration with ether
