Step 2. The method follows that of S5; 2, 6-piperidinedimethanol (3.80 g, 26.21 mmol), iodoacetonitrile (5.24 g, 31.45 mmol), Et3N (4. 38 mL, 31.45 mmol) and dry DMF (20 mL). Purification by flash chromatography using CH2CI2/CH30H (9: 1) as eluent afforded the title compound as a straw-coloured oil (2.5 g, 53 %). FAB MS, m/z (M+H) + 185. The iodoacetonitrile was prepared by the use of the Finkelstein reaction. BrCH2CN (3.77 g, 0.0314 mmol) was added dropwise to a stirred solution of Nal (4.71 g, 0.031 mmol) in acetone. Precipitation of NaBr occurred within a few minutes and indicated that exchange of the halides had taken place. Sodium bromide was filtered off, and the acetone was removed in vacuo. Crude yield (5.24 g, 100 %).
