Reaktionsschritte

To 2-chloro-4-methoxyquinoline (0.576 g, 3 mmol) was added 1-amino-3,3-diethoxypropane (0.515 g, 3.5 mmol) and diisopropylethylamine (5 ml). The mixture was stirred under argon at 95° C. for 60 h. Volatile material was removed in vacuo and the residue partitioned between ethyl acetate and water. The ethyl acetate soluble material was purified by chromatography on silica gel eluting with 0-10% (9:1 MeOH/NH3) in dichloromethane to give the title compound as a yellow gum (110 mg, 12%). δH (CD3OD) 1.1 (6H, t), 1.85 (2H, m), 3.35-3.7 (6H, m), 3.9 (3H, s), 4.6(1H, t), 6.05(1H, s), 7.0(1H, t), 7.35 (1H, t), 7.45 (1H, d), 7.8 (1H, d); MS (ES+) 305 (63%, MH+). 259 (28), 213 (42), 187 (100).
