実験手順
The nitroaniline derivative (10.0 g, 0.045 mol) (obtained in step 1 above) was hydrogenated using 10% Pd-C (1.5 g) in ethanol (45 mL), by an analogous procedure to that described in preparation 1 (step 4) to yield 4-(piperazin-1-yl)-1, 2-phenylenediamine (8.0 g, 93%) as a brown viscous oil. IR (Neat) 3342 cm-1 ; 1H NMR (CDCl3) δ 2.80 (brs, 5H, NH), 3.00 (m, 8H, 4×NCH2), 6.30 (d, J=8.2 Hz, 1H), 6.38 (s, 1H), 6.62 (d, J=8.0 Hz, 1H); Mass (m/z) 192 (M+.).
後処理
