Diisopropylethylamine → 8-methyl-2-phenyl-3-((1S)-1-(9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-ylamino)ethyl)-isoquinolin-1(2H)-one

Participants

Reaction Steps

3-(1-Aminoethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one (compound 4704) (200 mg, 0.72 mmol), 6-chloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (344 mg, 1.44 mmol) and DIPEA (279 mg, 2.16 mmol) were dissolved in n-BuOH (20 ml), and the resulting mixture was stirred at reflux for 16 h. The reaction mixture was concentrated in vacuo and purified by flash column chromatography on silica gel (eluting with 30% to 50% Hex/EA) to afford the desired product, 8-methyl-2-phenyl-3-((1S)-1-(9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-ylamino)ethyl)isoquinolin-1(2H)-one (compound 4901) (207 mg, 60% yield) as a white solid.
