Triethylamine → (S)-N-(1-(8-chloro-1-(2-morpholinoethyl)isoquinolin-3-yl)ethyl)thiazolo[5,4-d]pyrimidin-7-amine

Participants

Reaction Steps

A mixture of (S)-1-(8-chloro-1-(2-morpholinoethyl)isoquinolin-3-yl)ethanamine 71 (100 mg, 0.31 mmol, 1 eq), 7-chlorothiazolo[5,4-d]pyrimidine (E-4) (108 mg, 0.63 mmol, 2 eq) and triethylamine (130 mg, 1.25 mmol, 4.0 eq) in n-BuOH (40 mL) was stirred at reflux for 16 h. The reaction mixture was cooled to RT and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (1-5% MeOH-DCM) to afford the product (S)—N-(1-(8-chloro-1-(2-morpholinoethyl)isoquinolin-3-yl)ethyl)thiazolo[5,4-d]pyrimidin-7-amine 72. ESI-MS m/z: 455.0 [M+H]+.
