실험 절차

In Example 5, 0.2006 grams (1.60 mmole) of 6-(hydroxymethyl)pyridine-2(1H)-one was suspended in 160 mL of THF in a 250 mL round bottom flask under the presence of argon gas. Then, 0.0671 g (1.68 mmole) of 60% NaH dispersed in mineral oil was added and the solution was stirred for 20 min. 0.19 mL (1.58 mmole) of 4-fluorobenzoyl chloride was dissolved in 20 mL of THF and added dropwise into the alcohol reaction mixture at a rate of 10 μL/min. The reaction stirred for 48 hours under the presence of argon gas before being quenched with 20 mL of water. The reaction was washed with ethyl acetate (4×20 mL), the organic layers combined, washed with saturated NaHCO3 (4×20 mL), washed with Brine (3×20 mL) and finally dried over MgSO4. The solvent was removed in vacuo to produce a dull yellow solid. The compound was purified by column chromatography(methanol/dichloromethane). The result was a fine white powder.
