Ethanol → 2-(4-Methoxypyrimidin-5-yl)propanoic acid

Participants

Reaction Steps

To a stirred solution of 0.21 g (1.06 mmol) of methyl 2-(4-methoxypyrimidin-5-yl)propanoate from Step B above in 0.5 mL of water and 1.5 mL of ethanol was added 81 mg (1.9 mmol) of lithium hydroxide hydrate. The reaction mixture was stirred at ambient temperature for 2 h then concentrated in vacuo to remove all volatiles. The residue was diluted with 3 mL of 2.0 N aqueous hydrogen chloride and then concentrated in vacuo to remove all volatiles to yield the title compound as an off white solid (70 mg, 36%). 1H-NMR (500 MHz, CD3OD) δ: 8.67 (s 1H), 8.4 (s, 1H), 4.07 (s, 3H), 3.9 (q, J=7 Hz, 2H), 1.58 (d, J=7 Hz, 3H). LC-MS: m/z (E/S) 183 (MH)+.
