実験手順

To a stirred solution 5-benzyloxy-6-hydroxy-2-(1-pyridin-2-yl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-cyclopropyl-amide (450) (120 mg, 0.199 mmol) of in tetrahydrofuran (6 mL), was added 1N aqueous HCl (1.5 mL) and stirring was continued for 1 h at room temperature. After completion of the reaction, volatiles were removed and the residue was diluted with water (10 mL) and the pH was adjusted to pH 8 by using NaHCO3 and the mixture extracted with ethyl acetate (2×30 mL). The combined extracts were dried and concentrated. The resulting crude product was purified by normal silica gel (100-200 mesh) column chromatography using 50-60% ethyl acetate in hexane as gradient polarity mobile phase to get 5-benzyloxy-6-hydroxy-2-(1-pyridin-2-yl-cyclopentylmethyl)-pyrimidine-4-carboxylicacidcyclopropyl-(2-hydroxyethyl)-amide (451) (80 mg, 82%) as a colorless gummy liquid.
