Reaction Steps

To a stirred solution of 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-cyclopropyl-amide (284) (430 mg, 0.69 mmol) in tetrahydrofuran (20 mL) was added 1N HCl (3.5 mL. 3.48 mmol) at room temperature and the reaction mixture was stirred for 30 min. After completion of the reaction, solid NaHCO3 was added, basified up to pH 8. Water (10 mL) was added and the mixture was extracted with ethyl acetate (3×30 mL). The organic part was dried and concentrated to get 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid cyclopropyl-(2-hydroxyethyl)-amide (285) (300 mg, 88.4%) as a light yellow sticky mass.
