Procedure

38.2 g of crude trans-methanesulfonic acid 4-(tert-butyl-dimethyl-silanyloxymethyl)-cyclohexylmethyl ester and 16.7 g (340 mmol) of sodium cyanide dissolved in 380 ml of N,N-dimethylformamide were stirred for 2 hours at 80° C. After cooling the reaction mixture down to room temperature, it was partitioned between Et2O and water. The organic layer was dried over magnesium sulfate and concentrated under reduced pressure and the residue then chromatographed on silica gel with a 9:1 v/v mixture of hexane and ethylacetate as the eluent giving 24.2 g (78% over two steps) of pure trans-[4-(tert-butyl-dimethyl-silanyloxymethyl)-cyclohexyl]-acetonitrile as colorless viscous oil, MS: 290 (MNa+).
