Procedure

To a solution of isobutyrric acid (49 l, 0.53 mmol) in CH2Cl2 (1.5 ml), N-cyclohexylcarbodiimide, N′-methyl polystyrene (0.4 g, loading 2 mmol/g, 0.798 mmol), Nhydroxybenzotriazole (0.072 g, 0.53 mmol) and a solution of 2-(2-amino-1,3-thiazol-4-yl)-N-(5-isopropyl-1,3-thiazol-2-yl)acetamide (0.075 g, 0.266 mmol) in CH2Cl2/DMF (0.4 ml/0.6 ml) were added. The reaction mixture was maintained under stirring at room temperature for about 8 days. After this time, PS-Trisamine (0.44 g, loading 3.62 mmol/g, 1.596 mmol) was added, stirring was continued for about 6 hours and then the mixture was filtered. The resin was washed with CH2Cl2 (1 ml×5), the organic layers were combined and evaporated to dryness to give, after trituration with diisopropyl ether the title compound.
