반응 단계

Add tetra-N-butylammonium azide to a solution of triphenylphine (11 g, 42 mmol) and 1,4-cyclohexadiene-2,2-dicarbonitrile,4,5-dichloro-3,6-dioxo-(9 g, 40 mmol) in dichloromethane (150 mL) under ice-bath cooling. Then add 1-(6-fluoro-4-iodo-pyridin-3-yl)-ethanol (6.7 g, 25.1 mmol) to the above solution. Stir the mixture at room temperature for 1 hour. Concentrate the mixture in vacuo to about 50 mL. Purify the residue by flash column chromatography (hexane to 20% ethyl acetate in hexane as gradient) to give target product as colorless oil (5.7 g, 78%). MS (ES) m/z 293 [M+1]+.
