실험 절차

3-Amino-5-[(7-chloroquinolin-4-yl)amino]benzonitrile hydrochloride prepared from step B of example 19 (200 mg, 0.68 mmol), 1-(2-chloroethyl)piperidine hydrochloride (125 mg, 1 eq), K2CO3 (468 mg, 5 eq) and DIEA (0.11 mL, 1 eq) were refluxed in 30 mL of acetonitrile for 72 h. The reaction mixture was then filtered. The filtrate was evaporated and the residue was purified by flash chromatography on silica gel (AcOEt/MeOH//100/0 to 95/5) to yield expected compound as a yellow powder (8 mg, 3% yield). m/z (ESI) 406.2 [M+H]+.
