실험 절차

To a solution of 2-chloro-4-morpholinothieno[2,3-d]pyrimidine-6-carbaldehyde (1.1 g, 3.9 mmol) in 1,2-dichloroethane (20 mL) was added 1-(2-hydroxyethyl)piperazine (0.7 mL, 5.4 mmol), and AcOH (3.9 mmol). After the reaction mixture stirred 10 min at room temperature, Na(OAc)3BH (4.6 mmol) was added then the mixture stirred 72 h at room temperature. The reaction was quenched by the addition of saturated aqueous NaHCO3. The organic layer was separated and the aqueous layer was extracted with CH2Cl2. The combined organics were dried over Na2SO4 and concentrated in vacuo. 2-(4-((2-chloro-4-morpholinothieno[2,3-d]pyrimidin-6-yl)methyl)piperazin-1-yl)ethanol was purified by silica gel chromatography (0-20% MeOH in CH2Cl2) to afford 2-(4-((2-chloro-4-morpholinothieno[2,3-d]pyrimidin-6-yl)methyl)piperazin-1-yl)ethanol (0.8 g).
