実験手順

Triethylamine (24.0 mL, 172.58 mmol) was added to a solution of tert-butyl 2-[(3-amino-7-benzyloxyquinolin-4-yl)amino]ethylcarbamate (35.25 g, 86.29 mmol) in dichloromethane (400 mL) and stirred at ambient temperature. Chloroacetyl chloride (6.87 mL, 86.29 mmol) was quickly added at ambient temperature to avoid splashing and was stirred for 10 minutes. The reaction mixture was concentrated under reduced pressure, dissolved in ethanol (500 mL), and stirred for 2 days at ambient temperature. The mixture was concentrated under reduced pressure and the residue was recrystallized from dichloromethane to afford 6.23 g of tert-butyl 2-(7-benzyloxy-2-chloromethyl-1H-imidazo[4,5-c]quinolin-1-yl)ethylcarbamate.
