Participants

Reaction Steps

To 2-((4-fluorophenyl)(hydroxy)methyl)-7-(trifluoromethyl)quinazolin-4-ol (2000 mg, 5.89 mmol) was added Dess-Martin periodinane (3000 mg, 7.07 mmol) in acetonitrile (25 mL) and the mixture was stirred at rt for 2 h. To the crude mixture was added aq sodium bicarbonate solution and the mixture was stirred for 0.5 h. The resulting brown precipitate was collected, washed with diethyl ether and dried under high vacuum to afford (4-fluorophenyl)(4-hydroxy-7-(trifluoromethyl)quinazolin-2-yl)methanone (2.57 g, quantitative yield) LC-MS (ESI) m/z 336 (M+Na)+.
