Procedure

N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (39 mg, 0.2 mmol) is added to a stirred ice cold solution of N-[4-(3-{2-methoxy-6-[2-(4-trifluoromethoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-phenyl)-tetrahydro-pyran-4-carboxylic acid (100 mg, 0.19 mmol), methanesulfonamide (19.3 mg, 0.2 mmol) and 4-dimethylaminopyridine (23.6 mg, 0.19 mmol) in dry DCM under nitrogen. The reaction mixture is stirred overnight at room temperature and concentrated in vacuo. The residue is dissolved in ethyl acetate, washed with 0.1 N HCl, brine and water, dried over sodium sulfate, filtered and concentrated in vacuo. The residue is purified by chromatography (SiO2 packed column), eluting with ethyl acetate/heptane to afford N-[4-(3-{2-methoxy-6-[2-(4-trifluoromethoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-phenyl)-tetrahydro-pyran-4-carbonyl]-methanesulfonamide [86 mg, Example 84(a)]. LCMS: RT=2.52 minutes, LCMS: 595 (M+H). IC50=0.7 nM
