Procedure
To a solution of 8-fluoro-4-(2-hydroxyethyl)-3-oxo-3,4-dihydro-2H-quinoxaline-1-carboxylic acid 2-methyl-4-(2,3,4,5-tetrahydrobenzo[b]azepine-1-carbonyl)benzylamide from Example 9 (105 mg, 0.20 mmol) in dichloromethane (5 ml) was added Dess-Martin periodinane (100 mg, 0.24 mg). The mixture was stirred for 2 h and evaporated. The residue was taken up in chloroform and water and separated. The organic layer was dried and evaporated. The residue was purified by flash chromatography on silica (eluant methanol:dichloromethane 4:96) to give a white solid; yield 73 mg, 69%.
