Procedure

In 20 g of acetonitrile, 5.4 g (0.01 mole) of the intermediate, triphenylsulfonium 1,1-difluoro-2-hydroxy-ethanesulfonate (purity 78%), 1.0 g (0.01 mole) of triethylamine and 0.24 g (0.002 mole) of N,N-dimethylaminopyridine were dissolved and ice cooled. 2.6 g (0.012 mole) of 4-adamantanone-1-carbonyl chloride, prepared above, was added dropwise to the solution at a temperature below 5° C. It was stirred at room temperature for 1 hour. Dilute hydrochloric acid (1 g of 12N hydrochloric acid in 10 g of water) was added to the solution. The acetonitrile was distilled off in vacuum, after which 50 g of dichloromethane, 50 g of methyl isobutyl ketone, and 20 g of water were added to the residue. The organic layer was separated and washed with 20 g of water. The solvent was distilled off in vacuum. Ether was added to the residue for crystallization. The crystals were filtered and dried, obtaining the target compound. 4.8 g (yield 80%). On 1H-NMR analysis, methyl isobutyl ketone and ether were observed as a trace amount of residual solvent.
