Yield:89960-36-1 97.6%
Reaction Conditions:
with lithium hydroxide monohydrate;water in methanol at 20; for 4 h;
Steps:
14 1-Benzyl-2-oxo-l,2-dihydropyridine-3-carboxylic acid (lnt-12)
To a mixture of compound lnt-11 (500 mg, 2.05mmol) in MeOH (1 mL) and H2O (1 mL) was added Li0H-H20(l72 mg, 4.10 mmol, 2.0eq) and the mixture was stirred at room temperature for 4 h. The mixture was concentrated in vacuo and the pH was adjusted to 3~4 with aqueous HC1 (1 M). The resulting suspension was filtered and the isolated solid was dried to afford compound lnt-12 (460 mg, 97.6%) as a white solid. ESI-MS (EI+, m/z): 230.1.
