Procedure: The compound obtained in Example 19-3 was treated with an anion-exchange resin. The treated product was dissolved in chloroform (4.0 ml) and added with n-hexyl chloroformate (manufactured by Tokyo Kasei Kogyo Co., Ltd.) (0.054 ml) and triethylamine (0.060 ml), followed by stirring at room temperature for 16 hours. After completion of the reaction, the solvent was distilled off. The residue was added with chloroform, washed with water and saturated saline solution, and dried with anhydrous sodium sulfate, followed by distilling the solvent off. Subsequently, the residue was purified through silica gel column chromatography (chloroform/methanol), thereby obtaining the subject compound (66.6 mg) as a white solid. After completion of the reaction the solvent was distilled off The residue was added with chloroform washed with water and saturated saline solution dried with anhydrous sodium sulfate by distilling the solvent off Subsequently, the residue was purified through silica gel column chromatography (chloroform/methanol)

Procedure: 4-(2-(5-Amino-8-methylbenzo[f][1,7]naphthyridin-2-yl)ethyl)phenyl hexyl carbonate was prepared from 4-(2-(5-amino-8-methylbenzo[f][1,7]naphthyridin-2-yl)ethyl)phenol (from Example 170) following the procedures described for Example 138, but using hexyl carbonochloridate. LRMS [M+H]=458.2.

Procedure: A mixture of 5-aminomethyl-2-(2,6-dioxo-piperidin-3-yl)-isoindole-1,3-dione hydrochloride (1.0 g, 3.1 mmol), hexyl chloroformate (0.51 g, 3.1 mmol), and triethylamine (0.63 g, 6.2 mmol) in THF (35 mL) was stirred at 40° C. under nitrogen for 3 hours. The mixture was cooled and diluted with ethyl acetate (100 mL), washed with water (3×100 mL), and evaporated. The residue was chromatographed in methylene chloride-methanol gradient, eluting the product at 19:1 methylene chloride-methanol. This material was further purified by preparative HPLC, using a 50-50 acetonitrile-water isocrat, and providing 0.40 g as a white solid, in 31% yield; mp 111-113° C.; HPLC, Waters Symmetry C-18, 3.9×150 mm, 5 μm, 1 mL/min, 240 nm, 50/50 CH3CN/0.1% H3PO4, 5.08 (99.11%); 1H NMR (DMSO-d6) δ 1.11-1.57 (m, 1H), 2.02-2.07 (m, 1H), 2.46-2.63 (m, 2H), 2.84-2.96 (m, 1H), 3.97 (t, J=8.3 Hz, 2H), 4.35 (d, J=6.0 Hz, 2H), 5.15 (dd, J=12.9 Hz, J=5.4 Hz, 1H), 7.72-7.77 (m, 2H), 7.84-7.90 (m, 2H), 11.13 (s, 1H); 13C NMR (DMSO-d6) δ 13.8, 22.0, 25.0, 28.6, 30.8, 30.9, 43.5, 49.0, 64.0, 121.6, 123.5, 129.8, 131.6, 133.2, 147.9, 156.6, 167.0, 167.1, 169.8, 172.7; Anal.
