実験手順

A mixture of 3-(3-quinolinyl)-2-propyn-1-ol (prepared as described in J. Med Chem. 1996, 39, 3179) (360 mg, 1.96 mmol) and the Dess-Martin reagent (1.00 g, 2.36 mmol) in dichloromethane (10 mL) was stirred at RT for 1.5 h. The solution was washed with sat. aq. NaHCO3 and brine, dried (MgSO4), and concentrated. Purification by chromatography (SiO2, 1:4 hexane/ethyl acetate) yielded 258 mg (72%) of the title compound. MS 182 (M+H)+.
