Reaction Steps

tert-Butyl 5-(benzyloxy)-6-hydroxy-2-(2-methyl-2-phenylpropyl)pyrimidine-4-carboxylate (55) (260 mg, 598 μmol, Eq: 1.00) was stirred in tetrahydrofuran/water. Lithium hydroxide monohydrate (126 mg, 2.99 mmol, Eq: 5) was added. The reaction mixture was heated at 85° C. for 7 hours, cooled, and stirred at room temperature for 16 hours. 1N HCl was added until precipitate forms (about 10 ml). The mixture was diluted with water, extracted three times with ethyl acetate, washed with brine and dried over magnesium sulfate. The solvent was removed on a rotary evaporator to give 5-(benzyloxy)-6-hydroxy-2-(2-methyl-2-phenylpropyl)pyrimidine-4-carboxylic acid (56) as a white solid (155 mg, 68%).
