(7-(4-(4-(2,3-dichlorophenyl)piperazin-1-yl)butoxy)-2-oxo-3,4-dihydroquinolin-1(2H)-yl)methyl isopentyl carbonate (Example 10: Compound 84) To a solution of phosgene (20% in toluene, 54 mL, 110 mmol) in tetrahydrofuran (100 mL) was added a solution of 3-methyl-1-butanol (1.7 mL, 15.7 mmol) in tetrahydrofuran (50 mL) over 1 hour. After 4 hours the volatiles were removed under vacuum and the residue added to a solution of the hemi-aminal A1 (3 g, 4.7 mmol), 4-dimethylaminopyridine (0.3 g, 1.9 mmol), pyridine (10 mL) and triethylamine (1.3 mL, 9.4 mmol) in dichloromethane (30 mL). After being stirred for 72 hours, the reaction mixture was diluted with ethyl acetate (100 mL) and washed with 5% aqueous NaHCO3/brine (1:1, 100 mL). The organic phase was dried over MgSO4, filtered and evaporated under vacuum. The residue was further purified by chromatography on silica eluting with ethyl acetate/dichloromethane/methanol (1:1:0.1) to give the desired product as a yellow oil (1.54 g, 55% yield). 1H NMR (CDCl3, 300 MHz) δ 1.90-1.95 (m, 6H), 1.50-1.60 (m, 4H), 1.65-1.79 (m, 2H), 1.79-1.89 (m, 2H), 2.50 (t, 2H), 2.60-2.72 (m, 6H), 2.82-2.90 (m, 2H), 3.02-3.11 (m, 4H), 3.98 (t, 2H), 4.21 (t, 2H), 5.92 (s, 2H), 6.56 (dd, 1H), 6.67 (d, 1H), 6.95-7.00 (m, 1H), 7.05 (d, 1H), 7.13-7.19 (m, 2H); m/z (M+H) 592.48 and 594.46.
