実験手順
The title compound was prepared following the procedure described in step-3 of Intermediate-2 using methyl 2-chloro-4-fluoro-3-(pivalamidomethyl)benzoate (350 mg, 1.16 mmol) in THF:MeOH:H2O (3:2:1; 6 mL) and NaOH (93 mg, 2.32 mmol) to afford 250 mg of the title product. 1H NMR (300 MHz, DMSO-d6): δ 12.55 (br s, 1H), 7.78 (m, 2H), 7.32-7.26 (t, J=8.7 Hz, 1H), 4.38 (d, J=4.5 Hz, 2H), 1.07 (s, 9H).
