实验步骤: 1,5-Diaminopentane (0.75 g, 7.21 mmol) was stirred while tritylsulfanyl-acetic acid methyl ester (2.53 g, 7.27 mmol) was added slowly.

实验步骤: Under an argon atmosphere, 1,5-diaminopentane (25 g, 0.24 mol) and benzamide (9.9 g, 0.081 mol) were combined and heated at reflux overnight. The reaction mixture was concentrated under vacuum to remove the excess diamine. The residue was distilled at about 210° C. at 12 torr (16×102 pascals) to provide 11.8 g of N-(5-aminopentyl)benzamide as a colorless oil. heated at reflux overnight The reaction mixture was concentrated under vacuum to remove the excess diamine The residue was distilled at about 210° C. at 12 torr (16×102 pascals)

实验步骤: Benz[d]indeno[1,2-b]pyran-5,11-dione (4d) (0.100 g, 0.403 mmol) was treated with 1,5-diaminopentane (0.206 g, 2.014 mmol) in CHCl3 (40 mL) and the reaction mixture was heated at reflux for 16 h. The reaction mixture was allowed to cool to room temperature and washed with water (3×15 mL). The solution was dried over sodium sulfate, filtered, and treated with 2 M HCl in Et2O (5 mL). After 30 film, the reaction mixture was filtered and the filter pad was washed with CHCl3 (50 mL) and hexanes (50 mL) to provide an orange solid (0.122 g, 82%): mp 265-268° C.

With stirring, benzyloxycarbonyl chloride (3.67 ml., 4.17 g., 0.0245 mol) was added dropwise, maintaining the temperature near 0°. The mixture was warmed to room temperature, washed 2×50 ml. 5% HCl, 1×50 ml. saturated NaHCO3, and 1×50 ml. brine, dried (MgSO4) and stripped to yield title product as a white solid., 4 g.; 1H-nmr (CDClhd 3) includes delta 5.2 ppm (s, 4H, two benzyl CH2 groups).
