This ester was again deprotonated with LDA in THF, as described above, and at −78° C. a solution of N-fluoro benzenesulfonimide (1.1 equivalents) in THF was added dropwise. The mixture was allowed to warm to room temperature, quenched with saturated ammonium chloride solution, and worked up as above. Chromatography on silica gel with 5% ethyl acetate in hexane provided methyl 2-(2-butynyl)-2-fluorodecanoate as an oil.
