Reaktionsschritte
To a 0° C. solution of 4-chloro-3-nitroquinoline (7.50 g, 36.0 mmol) and triethylamine (7.5 mL, 54 mmol) in dichloromethane (150 mL) was added 8-(aminomethyl)-1,4-dioxaspiro[4.5]decan-8-ol (8.10 g, 43.1 mmol). The reaction was allowed to warm to rt and stir overnight, then was concentrated under reduced pressure to yield a yellow solid. The solid was stirred in water (500 mL) and was isolated by filtration, dried under vacuum, and recrystallized from toluene (280 mL) to yield 8-{[(3-nitroquinolin-4-yl)amino]methyl}-1,4-dioxaspiro[4.5]decan-8-ol as bright yellow crystals (12.3 g, 72%).
