反応手順
2-(N′-Benzylidene-hydrazino)-benzoic acid (5.0 g, 20.81 mmol) in 1:1 tetrahydrofuran and methanol (50 mL) was reacted with a solution of trimethylsilyl diazomethane in hexanes (2.0M, 12 mL, 25.0 mmol) at 0° C. for 1 hour then stirred at 25° C. for 48 hours. The solvent was removed under vacuum to give methyl 2-[2-benzylidenehydrazino]benzoate as a solid (6.00 g, 100%). 1H NMR (300 MHz, DMSO-d6) ppm 3.87 (s, 3 H) 6.84 (td, J=7.54, 1.10 Hz, 1 H) 7.41 (m, 3 H) 7.54 (m, 1 H) 7.74 (m, 3 H) 7.86 (dd, J=8.09, 1.47 Hz, 1 H) 8.21 (s, 1 H) 11.02 (s, 1 H).
