实验过程
1,2-Bis(methylsulfonyl)-1-(2-chloroethyl)-2-[(4,5-dimethoxy-2-nitrobenzyloxy)carbonyl]hydrazine (compound 12) was prepared by reacting 4,5-dimethoxy-2-nitrobenzyl chloroformate with compound 2 using a procedure similar to that described for compound 10d. The product was recrystallized from ethanol, and the Mp was about 154° C. Yield was about 17.6% by weight. 1H NMR (acetone d6): δ 7.7 and 7.4 (2H, 2s, aromatic H), 5.8 (2H, d, ArCH2), 3.7-4.1 (4H, m, CH2CH2Cl), 3.9-4.0 (6H, 2s, 2 OCH3), and 3.5 and 3.2 (6H, 2s, 2 CH3SO2).
