Magnesium monoxide → HCID 19080720, compound

Participants

Reaction Steps

To a solution of 1.4 g of 1,1-bis-(2-chloro-4-trifluoromethylpyrid-3-yl)methanol in 12 ml of methanol were added 0.8 g of magnesium oxide and 0.3 g of 5% palladium on carbon. This mixture was then shaken on a Parr hydrogenation apparatus overnight under 50 psi of hydrogen. The palladium catalyst and magnesium oxide were removed via filtration through dicalite, and the methanol filtrate was concentrated in vacuo to afford 1.6 of a yellow solid. This solid was dissolved in 25 ml of methylene chloride. The methylene chloride solution was washed with water, dried over magnesium sulfate, filtered, and concentrated in vacuo to afford 0.93 g of 1,1-bis-(4-trifluoromethylpyrid-3-yl)methanol as a yellow solid.
