الإجراء التجريبي

1″,5″-[Bis-(4′-O-demethyl-4β-N-4-desoxypodophyllotoxin)] naphthalene diamine (4b) was prepared according to the method described earlier, employing 1,5-diamino naphthalene (80 mg, 0.5 mmol), Bu4N30I−(185 mg, 0.5 mmol), Et3N (150 mg, 1.5 mmol) and 4′-O-demethyl-4β-bromo-4-desoxy podophyllotoxin (462 mg, 1.0 mmol) to give the product in 76% yield. Spectral data: 1H NMR (CDCl3); 7.22-7.28 (d, 2H), 7.10-7.19 (t, 2H), 6.73 (S, 2H), 6.58 (S, 2H), 6.50 6.55 (d, 2H), 6.33 (S, 4H), 5.98 (ABq, 4H), 5.34 (S, 2H), 4.87 (br, 2H), 4.63-4.70 (d, 2H), 4.52-4.59 (d, 2H), 4.36-4.48 (t, 2H), 3.85-3.95 (d, 2H), 3.82 (3, 6H), 3.20-3.31(dd, 2H), 2.98-3.16 (m, 2H); FAB MS: m/z 922 (M+); mp. 238-240° C.
