反応手順

A mixture of 6-(2-furyl)-1H-purine-2-amine (50 mg, 0.25 mmol) and triphenylphosphine polystyrene (0.21 g, 0.62 mmol) in anhydrous DMF (0.5 mL) and anhydrous THF (2 mL) was treated with 2-(2-hydroxyethyl)pyridine (61 mg, 0.50 mmol), shaken at room temperature for 10 min, treated with di-tert-butyl azodicarboxylate (0.115 g, 0.50 mmol), shaken for 16 h, filtered and the filtrate concentrated in vacuo and purified by chromatography [SiO2; CH2Cl2-MeOH (100:5)] to give the title compound (36 mg, 47%) as an off-white solid.
