4-[5-Chloro-2-(1-hydroxymethylpropylamino)-pyrimidin-4-yl]-benzoic acid methyl ester (68 mg, 0.20 mmol) was dissolved in 4 mL THF. To this solution 41 mg of lithium hydroxide monohydrate in 2 mL water was added and the reaction mixture stirred for 3 days. The reaction mixture was diluted with 1N HCl and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrated to afford 4-[5chloro-2-(1-hydroxymethylpropylamino)-pyrimidin-4-yl]-benzoic acid as a yellow solid, 64 mg, 0.20 mmol. LCMS ES+=322.1.
