Reaction Steps
1H-Pyridin-2-one-6-carboxylic acid (2.51 g, 18 mmol) was suspended in dry THF (30 ml) and 1,2-dimethoxyethane (10 ml) under argon. Lithium aluminium hydride (1.0 M in diethyl ether) (30 ml, 30 mmol) was added and the mixture heated to reflux. After 67 h heating was stopped, the mixture cooled to 0° C. and acetic acid (7 ml) added. The solvent was removed in vacuo and the residue purified by flash column chromatography on silica gel, eluting with 20–30% methanol in dichloromethane, to give the title compound as tan needles (0.714 g, 32%); δH (400 MHz; CD3OD) 4.47 (2H, s), 6.38 (1H, d, J 6.8), 6.41 (1H, d, J 9.2), 7.56 (1H, dd, J 6.8, 9.2); m/z (ES+) 126 (100%, [MH]+).
