Reaction Steps

To a solution of N-(4-amino-3-hydroxy-4-oxo-1-phenylbutan-2-yl)-2-(5-phenyl-1H-imidazol-2-yl)nicotinamide (60 mg, 0.136 mmol) in a mixture of 2 ml of DMSO and 10 ml of dichloromethane IBX-polystyrene was added (371 mg, 0.408 mmol), and the reaction mixture stirred for 16 hours at room temperature. The polymer was filtered off, washed with dichloromethane, the combined organic layers washed with water, dried and evaporated to dryness. The remaining oily residue was treated with water to give a yellow solid which was filtered off and dried again. To a solution of the obtained solid in 20 ml of ethylacetate (EtOAc) two drops of 4N HCl in dioxane were added, and the resulting precipitate filtered off. Recrystallisation of the crude product from 15 ml of ethylacetate yielded 31 mg of the title compound as solid.
