Participants

Reaction Steps

To a solution of 2-{[(4-fluorophenyl)methyl]oxy}-5-formyl-N-3-pyridinylbenzamide (may be prepared as described in Example 82; 100 mg, 0.29 mmol) in acetone (10 ml) was added potassium permanganate (67.7 mg, 0.43 mmol) as a solution in 10 ml of water. The mixture was stirred at room temperature overnight. The mixture was quenched by adding 10 ml of 5% sodium sulfite solution. The solution was filtered through celite and mixed with 1 ml of acetic acid. The mixture was evaporated to a third volume, water (20 ml) was added and the mixture was filtered to yield the title compound as a white solid. This contains about 10% starting material and was used directly without further purification. 63 mg.
