실험 절차

A solution of 3-[3-(phenylmethyl)-1,2,4-oxadiazol-5-yl]-1-propanol (88 mg, 0.4 mmol) in THF (4 ml) was treated with 8-chloro-3-pentyl-7-(2-propen-1-yl)-3,7-dihydro-1H-purine-2,6-dione (100 mg, 0.34 mmol) and PPh3 (115 mg, 0.44 mmol) under nitrogen. DBAD (101 mg, 0.44 mmol) was added in one portion and the reaction left to react for 5 h. The mixture was degassed by applying a vacuum and then nitrogen was introduced. Pd(PPh3)4 (39 mg, 0.034 mmol) was added and the mixture degassed once more. Morpholine (294 μl, 3.4 mmol) was added and the mixture was stirred under nitrogen for 3 h. The mixture was partitioned between 2M HCl (aq) and EtOAc. The organic layer was separated, washed with brine, dried (MgSO4) and concentrated. The title compound was obtained as a white solid after purification by MDAP (64 mg, 42%).
