{2-[N′-(3,5-Diaminopyrazol-4-ylidene)hydrazino]phenyl}methanol was prepared using 2-[(2-hydroxymethylphenyl)hydrazono]malononitrile (0.100 g, 0.5 mmol) which was derived from 3-aminobenzyl alcohol (0.123 g, 1.0 mmol) and malononitrile (1.5 mmol) in a manner similar to that described in Example 2, and hydrazine hydrate. The title compound was obtained as a brown solid (32 mg, yield 28%); 1H NMR (ppm, 200 MHz, DMSO-d6) δ 4.51 (d, 2H), 5.20 (t, 1H), 6.0 (br s, 4H), 7.15 (d, 1H), 7.30 (t, 1H), 7.45-7.60 (m, 2H), 10.60 (br s, 1H).
