Example 66
To a solution of 7,8-dichloro-N-(morpholin-2-ylmethyl)-4-(1H-pyrazol-4-yl)quinolin-2-amine (20 mg, 0.053 mmol) in THF (1 mL) was added triethylamine (0.074 mL, 0.53 mmol) and acetyl chloride (0.0057 mL, 0.08 mmol) at 0° C. After 1 h at rt, the reaction was quenched by MeOH (0.1 mL). After evaporation, the crude was purified directly by column chromatography on silica gel to give 1-(2-(((7,8-dichloro-4-(1H-pyrazol-4-yl)quinolin-2-yl)amino)methyl)morpholino)ethan-1-one as a solid (7 mg) (MS: [M+1]+ 420.0).
The following compounds are prepared essentially by the same method described above to prepare I-221.
