5-(Benzyloxy)-N-(2-(tert-butyldimethylsilyloxy)ethyl)-6-hydroxy-N-isopropyl-2-(2-methyl-2-phenylpropyl)pyrimidine-4-carboxamide (57) (62 mg, 107 μmol, Eq: 1.00) was stirred in tetrahydrofuran (2 ml), HCl (aqueous) (161 μl, 161 μmol, Eq: 1.5) was added. The reaction mixture was stirred at room temperature for 3.0 hours, 160 μl 1N NaOH was added and the reaction mixture was diluted with water, extracted twice with ethyl acetate. The combined organic layers were washed with brine and dried over magnesium sulfate. Trituration in hexanes/ether was conducted to give 5-(benzyloxy)-6-hydroxy-N-(2-hydroxyethyl)-N-isopropyl-2-(2-methyl-2-phenylpropyl)pyrimidine-4-carboxamide (58) (32 mg, 64%).
