実験手順

A mixture of 2-chloro-6-morpholino-9-(tetrahydro-2H-pyran-2-yl)-9H-purine-8-carbaldehyde (245 mg, 0.696 mmol), 2-(4-piperidyl)-2-propanol (110 mg, 0.77 mmol) and sodium triacetoxyborohydride (162 mg, 0.77 mmol) in 1,2-dichloroethane (10 mL) was stirred at room temperature for 30 minutes. The reaction mixture was then diluted with saturated aqueous sodium bicarbonate. The aqueous layer was then extracted with DCM. The combined organic extracts were then washed with water, dried over sodium sulfate, filtered and concentrated. The crude product was purified by flash chromatography (0-100% gradient EtOAc-heptane) to give the title compound (328 mg, 98%). LCMS: M+H+=480.2.
