Participants

Reaction Steps

N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (60.4 mg, 0.31 mmol) is added to a stirred ice cold solution of 4-(3-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-phenyl)-tetrahydro-pyran-4-carboxylic acid [150 mg, 0.3 mmol, Example 80(a)], methanesulfonamide (30 mg, 0.31 mmol) and 4-dimethylaminopyridine (38.5 mg, 0.3 mmol) in dry DCM under nitrogen and the reaction mixture is stirred overnight, while warming to room temperature. The mixture is concentrated in vacuo, the residue is dissolved in ethyl acetate, washed with 0.1N 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-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-phenyl)-tetrahydro-pyran-4-carbonyl]-methanesulfonamide [65 mg, Example 80(b)].
