실험 절차
A solution of ethoxyacetyl chloride (857 mg, 6.99 mmol) in acetonitrile (5 mL) was added to solution of tert-butyl 2-[(3-amino-2-chloroquinolin-4-yl)amino]ethylcarbamate (2.14 g, 6.35 mmol) in acetonitrile (20 mL). After five minutes, the solution was cooled in an ice bath and a white precipitate began to form. After one hour, the precipitate was isolated by filtration and dried under vacuum to afford the hydrochloride salt of tert-butyl 2-({2-chloro-3-[(ethoxyacetyl)amino]quinolin-4-yl}amino)ethylcarbamate (2.50 g).
