실험 절차

This compound was synthesized by the procedure described above for Compound 2, reacting 7-methyl-1H-indole-2,3-dione (1.00 g, 6.21 mmol) with intermediate 2 (1.76 g, 7.76 mmol). The crude acid was purified as described above for Compound 3 to give Compound 6 as a bright yellow powder (0.774 g, 38% yield): 1H NMR (400 MHz, DMSO-D6) δ 2.65 (s, 3H) 4.33 (s, 2H) 7.35 (m, 4H) 7.44 (m, 2H) 8.30 (dd, J=8.1, 1.3 Hz, 1H).
