実験手順

A solution of 3-(N-Boc-piperidin-4-yl)propyl iodide 1-1 (5.0 g, 14.2 mmol) (preparation described in EP 478,328), 4-hydroxybenzaldehyde 1-2 (1.73 g, 14.2 mmol), Cs2CO3 (9.2 g, 28.4 mmol) and DMF (50 ml) was stirred at ambient temperature for 2.0 hours. The reaction mixture was diluted with ethyl acetate and then washed with H2O, sat. NaHCO3, 10% KHSO4, brine, dried (MgSO4) and concentrated. Flash chromatography (silica, 10% EtOAc/hexane) provided 1-3 as a white solid.
