Procedure
A mixture of 4-cyano-tetrahydro-thiopyran-4-carboxylic acid tert-butyl ester (206 mg) and NaIO4 (217 mg) in MeCN/water (3 mL/3 mL) was stirred between 0° C. and rt overnight; then the reaction was diluted with EtOAc, washed with dil. Na2SO3 solution, water and dil. NaCl solution respectively; EtOAc phase was dried over anhydrous sodium sulphate, filtered, concentrated and column-purified to give the desired product (193 mg). 1H NMR in CDCl3, δ in ppm: 3.2-2.6 (m, 6H), 2.4-2.1 (m, 2H), and 1.52 (s, 9H).
