Triphenylphosphine → HCID 21890160, compound

Participants

Reaction Steps

4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]phenol (100 mg), the compound (1) (59 mg), and triphenylphosphine (106 mg) were dissolved in tetrahydrofuran (3 ml) to prepare a solution. Diethyl azodicarboxylate (0.063 ml) was then added to the solution, and the mixture was stirred at room temperature for 3 hr. The solvent was removed by distillation under the reduced pressure. Water was added to the residue, and the mixture was extracted with ethyl acetate, followed by washing with saturated brine. The extract was then dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. The residue was purified by thin-layer chromatography using hexane/acetone for development. Diethyl ether was added to the purification product, and the precipitated crystal was collected by filtration and was washed to give the title compound (3 mg, yield 2%). Mass spectrometry value (FD-MS, m/z): 455 (M+)
