실험 절차

Racemic ethyl trans-4-[1-(5-bromo-1,3-thiazol-2-yl)-2-fluoro-1-hydroxyethyl]cyclohexane-carboxylate (107 mg, 0.281 mmol), N-[3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-4-(trifluoromethyl)pyrimidin-2-amine (231 mg, 0.610 mmol), X-Phos (56 mg, 0.120 mmol), Pd2(dba)3 (52 mg, 0.056 mmol), cesium carbonate (429 mg, 1.32 mmol), 1,4-dioxane (3.0 ml) and water (0.3 ml) were combined and the vial was evacuated and purged with nitrogen 3 times then heated to 100° C. for 2 h. The mixture was then filtered and diluted with EtOAc. The organic phase was washed with water, brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified on silica gel (0-10% MeOH in DCM) to afford racemic ethyl trans-4-{2-fluoro-1-hydroxy-1-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]ethyl}cyclohexanecarboxylate which was used without further purification. MS ESI calc'd. for C26H28F4N4O3S [M+H]+ 553. found 553.
