Versuchsvorschrift

To a solution of methyl (1S,4R)-4-{5-[3-(aminomethyl)-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl]-1,3-thiazol-2-yl}-4-hydroxy-2,2-dimethylcyclohexanecarboxylate (40 mg, 0.075 mmol) in anhydrous THF (1.5 ml) was added potassium cyanate (12.12 mg, 0.149 mmol, 2.0 equiv), acetic acid (8.55 μl, 0.149 mmol, 2.0 equiv), and water (4.5 ml). The mixture was stirred at 50° C. for 14 h. The reaction mixture was quenched with saturated aqueous NaHCO3 and extracted with EtOAc (40 ml). The organic layer were dried over Na2SO4, filtered and concentrated to provide the desired product, methyl (1S,4R)-4-[5-(3-[(carbamoylamino)methyl]-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-4-hydroxy-2,2-dimethylcyclohexanecarboxylate (40 mg, 88%), as an orange oil.
