Reaction Steps

To 5-benzyloxy-2-methoxyphenacyl bromide (4.0 g, 0.0119 mol) in 80 ml of dry dimethylformamide was added 3-hydroxypyridine (1.24 g, 0.013 mol, 1.1 equiv) followed by NaH (50% in oil, 0.604 g, 1.1 equiv). After stirring for 18 hours under N2, the mixture was poured into 500 ml of ice and water, and extracted 2×500 ml ethyl acetate. The organic layers were combined, washed 2×500 ml H2O and 1×300 ml brine, dried (Na2SO4), stripped to an oil, and chromatographed on silica gel using 1:1 hexane:ethyl acetate as eluant to yield 1.07 g of present title product as a solid; IR(KBr) 1670 cm-1;MS 349 (M+); 1H-NMR (300 MHz, CDCl3) delta (ppm) 3.95 (s, 3H), 5.1 (s, 2H), 5.35 (s, 2H), 2.0 (d, 1 H), 7.2-7.5 (m, 8H), 7.6 (d, 1H), 8.3 (d, 1H), 8.4 (d, 1H).
