Procedure

A 100-mL, round-bottom flask was charged with (S)-1-(6-bromo-5-hydroxy-2-methyl-3,4-dihydroquinolin-1(2H)-yl)ethanone (0.170 g, 0.60 mmol), 2-chloro-7-(tetrahydro-2H-pyran-2-yl)-7H-purine (0.200 g, 0.84 mmol), potassium carbonate (0.247 g, 1.79 mmol) and N,N-dimethylformamide (6 mL). The resulting mixture stirred overnight at 110° C. After cooling to room temperature, the reaction mixture was filtered, and the filtrate was concentrated under vacuum. The residue was purified by preparative thin layer chromatography (eluting with 1:1, ethyl acetate/petroleum ether) to afford 1-((S)-6-bromo-2-methyl-5-(7-(tetrahydro-2H-pyran-2-yl)-7H-purin-2-yloxy)-3,4-dihydroquinolin-1(2H)-yl)ethanone (0.200 g, 69%) as yellow oil. MS (ESI, pos. ion) m/z 486, 488 [M+H]+.
