Triphenylphosphine → HCID 21936093, compound

Participants

Reaction Steps

Diethyl azodicarboxylate (0.182 ml) was added dropwise to a stirred mixture of 4-(6-chloro-2,3-methylenedioxyanilino)-7-hydroxy-6-methoxyquinazoline (0.2 g), N-(2-hydroxyethyl)pyrrolidine (0.086 g), triphenylphosphine (0.303 g) and methylene chloride (3 ml) and the reaction mixture was stirred at ambient temperature for 15 minutes. The reaction mixture was evaporated and the residue was purified by column chromatography on silica using a 45:4:1 mixture of methylene chloride, methanol and a saturated methanolic ammonia solution as eluent. There was thus obtained the title compound (0.033 g) as a white solid; NMR Spectrum: (DMSOd6 and CF3CO2D) 1.9 (m, 2H), 2.1 (m, 2H), 3.2 (m, 2H), 3.7 (m, 2H), 3.8 (m, 2H), 4.05 (s, 3H), 4.6 (m, 2H),6.2 (s, 2H), 7.1 (d, 1H), 7.5 (s, 1H), 8.2 (s, 1H), 8.95 (s, 1H); Mass Spectrum: M−H− 441 and 443.
