Reaction Steps

3-Benzyloxy-2-methyl-1H-pyridin-4-one (1 g, 4.64 mmol) was mixed with potassium carbonate (0.2 g, 1.45 mmol) and CF3CH(OCH3)OH (4.34 g, 33.36 mmol) in sealed parallel synthesizer reactor and heated at 120° C. metal block temperature for 2 days. The mixture was cooled, and an additional amount of potassium carbonate (2 g, 14.5 mmol) and CF3CH(OCH3)OH (2 g, 15.30 mmol) was added. The mixture was again heated in a sealed tube at 120° C. for 60 hours. The mixture was cooled to room temperature and then evaporated to dryness. The residual material was purified by column chromatography (5% MeOH: dichloromethane) to give 3-benzyloxy-2-methyl-5-(2,2,2-trifluoro-1-hydroxy-ethyl)-1H-pyridin-4-one (0.55 g, 37.8% yield).
