96% | With 1H-imidazole; iodine; triphenylphosphine; In benzene; at 20℃; for 3h; | Imidazole (1.58 g, 23.2 mmol), triphenylphosphine (6.09 g, 23.2 mmol) and iodine (4.72 g, 18.6 mmol) were added to 1-(tert-butoxycarbonyl)piperidin-3-yl methanol (2.00g, 9.29 mmol) in benzene (50 mL). The mixture was stirred at room temperature for 3 hours. Subsequently, the reactionmixture was filtered through Celite and the solvent was evaporated. Water was added to the residue and the mixture was extracted with ethyl acetate. The extract was washed with brine and was dried over magnesium sulfate, followed by evaporation of the solvent. Purification of the residue by silica gel column chromatography (hexane: ethyl acetate = 20:1 -> 5:1) gave 2.91 g (96%) of the desired compound as a pale yellow oil. 1H NMR (400 MHz, CDCl3) delta 1.19-1.28 (1H, m), 1.40-1.52 (10H, m), 1.61-1.68 (2H, m), 1.91-1.95 (1H, m), 2.54-2.69 (1H, m), 2.79-2.84 (1H, m), 3.08 (2H, d, J = 6.7 Hz), 3.84 (1H, td, J = 13.4, 3.7 Hz), 3.97-4.13 (1H, m). FAB+(m/z): 326 (M+H). |
