Reaction Steps
Trans-4-(4-Bromo-3-methyl-benzenesulfonylamino)-cyclohexanecarboxylic acid [(R)-1-(4-fluoro-phenyl)-ethyl]-amide (Example 154, 100 mg, 0.201 mmol), Pd(dppf)Cl2. DCM (33 mg, 0.04 mmol), 2M Na2CO3 (1 ml, 2.01 mmol) and 2-methyl-4-pyridine boronic acid (41 mg, 0.302 mmol) were dissolved in DMF (1 ml) under N2. The reaction mixture was microwaved at 160° C. for 20 min., after which LCMS indicated that the reaction was complete. The mixture was diluted with EtOAc and washed with H2O (×2). The organic layer was concentrated in vacuo, and the crude material was purified via column chromatography using a biotage SP1 25+ S column with a gradient 100% EtOAc. Product fractions combined and concentrated to give the title compound as a white solid (31 mg, 30%). MS MH+ 510.1
