To a stirred solution of 5-benzyloxy-2-[1-(4-bromophenyl)-cyclopentylmethyl]-6-hydroxypyrimidine-4-carboxylic acid [2-(tert-butyl-dimethylsilanyloxy)-ethyl]isopropylamide (232) (1.0 g, 1.46 mmol) in tetrahydrofuran (10 mL) was added HCl (37% aqueous, 1.70 mmol) and the reaction mixture was stirred at room temperature for 1.5 h. After completion of the reaction, the mixture was diluted with ethyl acetate (30 mL), washed with water, separated and the organic phase dried over Na2SO4. After evaporation of the solvent, the crude product was purified by 100-200 silica gel column chromatography using 60% ethyl acetate in hexane followed by 5% methanol in dichloromethane as the eluent to obtain 5-benzyloxy-2-[1-(4-bromophenyl)-cyclopentylmethyl]-6-hydroxypyrimidine-4-carboxylic acid (2-hydroxyethyl)-isopropylamide (233) (0.7 g, 84%) as a white solid.
