To a stirred solution of 5-benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-oxetan-3-yl-amide (296) (240 mg, 0.39 mmol) in tetrahydrofuran (20 mL) was added a 1M solution of tetrabutylammoniumfluorid in tetrahydrofuran (1.2 mL, 1.16 mmol) at room temperature and stirring was continued for 60 min at room temperature. After completion of the reaction, the reaction mixture was concentrated and the residue purified by Combi-Flash column (eluted at 5% methanol in dichloromethane) to get 5-Benzyloxy-6-hydroxy-2-(1-phenyl-cyclopentylmethyl)-pyrimidine-4-carboxylic acid (2-hydroxyethyl)-oxetan-3-yl-amide (297) as an off-white sticky solid (150 mg, 76.68%).
