Reaktionsschritte

To a solution of 4-cyclopropyl-2,6-dimethylphenol (263 mg, 1.62 mmol) in 1-methyl-2-pyridone (3 mL) at 0° C. was added NaH (65 mg, 1.62 mmol). The reaction mixture was stirred at room temperature for 30 min and a solution of 2,6-dichloropurine (102 mg, 0.54 mmol) in 1-methyl-2-pyridone (2 mL) was added to the mixture. The mixture was heated at 100° C. for 16 h and then cooled to room temperature. The reaction was poured into ice water and extracted with CHCl3 (3×20 mL). The combined organic solution was washed with H2O (20 mL) and brine (20 mL), dried with Na2SO4, and concentrated to dryness. Silica gel chromatography (MeOH:CHCl3=5:95) yielded 114 mg (67%) of 2-chloro-6-(4-cyclopropyl-2,6-dimethylphenoxy)-9H-purine.
