Reaktionsschritte

In a similar manner to Step 2 of Example 16, 3-fluoro-N-(1-methyl-1-phenylethyl)benzamide (2.00 g, 7.77 mmol) was dissolved in THF (80 mL), and the solution was treated with TMEDA (3.8 mL, 24.9 mmol), sec-butyllithium-hexane solution (1.01 mol/L, 24.6 mL, 24.9 mmol) and DMF (1.30 mL, 17.1 mmol). The mixture was purified by slurry using diisopropylether to obtain 4-fluoro-3-hydroxy-2-(1-methyl-1-phenylethyl)isoindolinone (2.07 g, yield 93%).
