Versuchsvorschrift

To a stirring solution of the product of Example 1, Step D, 2-[(4-ethyl-2-fluorophenyl)amino]-3,4-difluorobenzoic acid (0.480 g, 1.626 mmol) in dichloromethane (15 mL) is added the product of Example 33, Step B, O-(2,2-dimethyl-[1,3]dioxan-5-yl)-hydroxylamine (0.287 g, 1.951 mmol), triethylamine (0.41 mL, 2.927 mmol), and benzotriazole-1-yl-oxy-tris-pyrrolidino-phosphonium hexafluorophosphate (1.02 g, 1.951 mmol) and allowed to stir at ambient temperature for 75 minutes. The reaction mixture was concentrated in vacuo and the affording residue was partitioned between ethyl acetate and water. The organic layers were washed twice with saturated sodium carbonate solution and twice with brine. The organic layer was collected, dried over sodium sulfate, filtered and concentrated in vacuo. N-(2,2-Dimethyl-[1,3]dioxan-5-yloxy)-2-(4-ethyl-2-fluoro-phenylamino)-3,4-difluoro-benzamide was isolated via silica column chromatography in 4:1 hexanes/ethyl acetate affording a white foam (0.423 g, 61.4%).
