Reaction Steps
2.0 g of 1-(4-chloropyrid-3-yl)-1-(thien-2-yl)methanol were dissolved in 100 ml of THF and the solution was cooled to 0° C. 3.2 g of trimethylacetyl chloride were added followed by the portionwise addition of 1.0 g of sodium hydride (60%) over a period of 15 minutes. The reaction mixture was allowed to warm to room temperature and then stirred overnight. 100 ml of a saturated ammonium chloride solution were added, and then this mixture was extracted twice with ethyl ether. The combined ether extracts were washed with a 5% aqueous solution of potassium carbonate, dried over magnesium sulfate, filtered, and then concentrated in vacuo to obtain 2.7 g of crude product. This material was then purified via chromatography on a silica gel column using ethyl acetatehexane (1:1) as the eluant to afford 1.9 g of 1-(4-chloropyrid-3-yl)-1-(thien-2-yl)-1-trimethylacetoxymethane as an oil.
