Reaction Steps

To a stirred solution of 5-benzyloxy-2-[1-(4-chlorophenyl)-cyclopentylmethyl]-6-hydroxypyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]-cyclopropyl-amide (325) (100 mg, 0.16 mmol) in tetrahydrofuran was added 1N HCl (5 ml) at room temperature and stirring was continued for 30 min wile silica thin layer chromatography was performed (60% ethyl acetate in hexane; Rf=0.4). After completion of the reaction, solid NaHCO3 was added to the reaction mixture which was basified up to about pH 8 and extracted with ethyl acetate (3×30 mL). The combined extracts were dried and concentrated to get 5-benzyloxy-2-[1-(4-chlorophenyl)-cyclopentylmethyl]-6-hydroxypyrimidine-4-carboxylic acid cyclopropyl-(2-hydroxyethyl)-amide (326) as a brown sticky mass. This was used in the next step without purification.
