Procedure

To a solution of 2-[(4-chlorophenyl)sulfanyl]ethanamine (15.32 g, 82 mmol, prepared from 4-chlorothiophenol and 2-chloroethylamine as described before) in DMF (247 ml) was added sequentially tetrahydro-2H-pyran-4-carboxylic acid (9.66 g, 74.2 mmol), EDC (15.65 g, 82 mmol) and HOAt (2.021 g, 14.85 mmol) and the reaction mixture was stirred at RT overnight. The reaction mixture was diluted with EtOAc, washed with 1N HCl, aq NaHCO3, 3M LiCl, dried over sodium sulfate, concentrated in vacuo and purified by flash chromatography (silica 1 kg, 50 to 100% EtOAc in hexane), to give N-{2-[(4-chlorophenyl)sulfanyl]ethyl}tetrahydro-2H-pyran-4-carboxamide (1825 g). MS: M+H=300. H1NMR (400 MHz, CDCl3) δ: 7.31 (d, J=9.9 Hz, 2H), 7.26 (d, J=9.9 Hz, 2H), 5.82 (br s, 1 H), 4.40-3.96 (m, 2H), 3.46 (dt, J=7.0, 7.0 Hz, 2H), 3.45-3.36 (m, 2H), 3.05 (t, J=7.0 Hz, 2 H), 2.34-2.26 (m, 1H), 1.82-1.65 (m, 4H).
