実験手順

To a solution of N-(4-Amino-3-hydroxy-4-oxo-1-phenylbutan-2-yl)-2-(1,3-benzothiazol-2-yl)pyridine-3-carboxamide (0.5 g, 1.16 mmol) in 1.5 ml of DMSO und 15 ml of dichloromethane 3.04 g N-cyclohexylcarbodiimid-N′-methylpolystyrole (1.9 mmol/g; 5.78 mmol) and 0.24 ml dichloroacetic acid (0.38 g, 2.89 mmol) were added, and the reaction mixture stirred over night at room temperature. For work up the polymer was filtered off, washed with dichloromethane, and the combined organic layers evaporated to dryness. Treatment with a mixture of n-hexane/ethylacetate, filtration and drying afforded 260 mg of the title compound, as white amorphous solid:
