Procedure
To a solution of 2-phenoxy-pyrimidine-5-carboxylic acid methyl ester (0.5 g, 2.17 mmol) in THF (10 mL) and water (5 mL) is added LiOH (105 mg, 4.35 mmol). The reaction is stirred at 0° C. for 1 h. The THF is evaporated and the aqueous reissue is washed with ether, acidified with 2 M aqueous HCl. The resulting precipitate is filtered and dried to afford 2-phenoxy-pyrimidine-5-carboxylic acid (0.34 g, 73%) as a solid. MS: 217 (M+H); 1H NMR (300 MHz, CDCl3): δ 7.20-7.35 (m, 3H), 7.47 (t, 2H) 9.16 (s, 2H).
