Procedure
To a solution of [4-(tert-butyldimethylsilanyloxymethyl)-cyclohexyl]-methanol (8.5 g) obtained in Step 1 in chloroform (85 mL) was added 1,1,1-tris(acetyloxy)-1,1-dihydro-1,2-benziodoxol-3-(1H)-one (Dess-Martin periodinane; 15.3 g) under ice-cooling, followed by stirring the mixture under ice-cooling for 2.5 hours. After addition of aqueous sodium sulfite solution and aqueous sodium bicarbonate solution, the reaction mixture was filtered through Celite, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine, dried and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate:hexane (volume ratio)=1:19 to 1:9) to give 4-(tert-butyldimethylsilanyloxymethyl)-cyclohexanecarbaldehyde (6.9 g).
