Triethylamine → (S)-3-(1-(2-amino-5-chloropyrimidin-4-ylamino)ethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one

Participants

Reaction Steps

A mixture of 3-(1-aminoethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one (compound 4704) (150 mg, 0.54 mmol), 2,4,5-trichloropyrimidine (119 mg, 0.65 mmol) and triethylamine (137 mg, 1.35 mmol) in n-BuOH (10 mL) was stirred at reflux for 2 h. The mixture was allowed to cool to room temperature and then concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (MeOH:CH2Cl2=1:100) to afford the desired product, (S)-3-(1-(2,5-dichloropyrimidin-4-ylamino)ethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one (2H)-one (compound 5101) (170 mg, 74% yield as a white solid.
