Versuchsvorschrift

Pyrrolidine (66 mg, 0.93 mmol) was dissolved in 50 ml of dry dimethylformamide under a nitrogen atmosphere and sodium hydride (60% in oil) (36 mg, 0.89 mmol) was added. The mixture was stirred for 1/2 hour. 5Benzyloxy-2-(4-benzyloxyphenyl)-3-((4-chlorobutoxy)methyl)-1-ethylpyrrolo[2,1,5-cd]indolizine (0.256 g, 0.443 mmol) was added and the mixture was stirred at 55-65° for 6 days. Ethanol (10 ml) was added dropwise, and the reaction mixture was diluted with 250 ml of water. The organic material was extacted into ethyl acetate (4×100 ml), and the combined oranic layers were washed with brine and dried over sodium solfate. The solvent was evaporated and the crude product was purified by column chromatography over silica gel 60, using 6% of methanol in dichloromethane as the eluent. Fractions containing the product were collected to afford 34 mg (12%) of 5-benzyloxy-2-(4-benzyloxyphenyl)-1-ethyl-3-((4-pyrrolidinobutoxy)methyl)pyrrolo[2,1,5-cd ]indolizine as an oil. MS(FAB): m/z613 (M+1). 1H-NMR (DMSO-d6, 300 MHz) δ: 1.27-1.49 (m, 11H); 2.50-2.56 (m, 6H); 3.05 (q, 2H); 3.40 (t, 2H); 4.71 (s, 2H); 5.20 (s, 2H); 5.58 (s, 2H); 7.20 (d, 2H); 7.31-7.64 (m, 14H); 7.95 (d, 1H).
