実験手順
General procedure for displacement reactions of 6-chloropurinones with aliphatic amines. To 10 mg (0.022 mmol) of 6-chloro-2-(6-fluoro-1H-benzo[d]imidazol-1-yl)-9-((R)-8-fluorochroman-4-yl)-7H-purin-8(9H)-one was added 0.6 mL of 1-butanol, followed by an aliphatic amine (0.1 mL), and the reaction mixture was stirred at 110° C. for 1-2 h (HPLC monitoring). Upon completion of the reaction, the mixture was left to cool to room temperature, was diluted with acetonitrile and filtered through a Nylon 0.45 μm filter. Preparative HPLC purification afforded, after solvent evaporation and drying, the desired product.
