Versuchsvorschrift

To a stirred solution of 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclohexylmethyl)-pyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-isopropylamide (257) (0.7 g, 1.13 mmol) in tetrahydrofuran (10.0 mL) was added HCl (0.062 g, 1.70 mmol) and the reaction mixture was stirred at room temperature for 1.5 h. After completion of the reaction, the mixture was extracted with ethyl acetate. The combined organic layer was washed with water, separated and dried over Na2SO4. After evaporation of the solvent, the crude product was purified by normal silica gel column chromatography (using 60% ethyl acetate in hexane followed by 5% methanol in ethyl acetate) to get 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclohexylmethyl)-pyrimidine-4-carboxylic acid (2-hydroxyethyl)-isopropylamide (258) (0.43 g, 75.0%) as a white solid.
