Procedure
1,2-Bis(methylsulfonyl)-2-(ethoxycarbonyl)-1-methylhydrazine (compound 7) was prepared from 1,2-bis(methylsulfonyl)-1-methylhydrazine and ethyl chloroformate using a procedure similar to that described for compound 6. The recrystallization solvent was ether-petroleum ether. Yield was 51.0%, and the Mp was approximately 89-90° C. 1H NMR (CDCl3): δ 4.4 (2H, q, OCH2), 3.5, 3.3 and 3.1 (9H, 3s, 2 CH3SO2 and NCH3), 1.4 (3H, t, OCCH3).
