実験手順

4-[4-(3-Pyrrolidin-1-ylpropoxy)phenyl]tetrahydro-2H-pyran-4-carbaldehyde (420 mg, 1.30 mmol, 1 wt), 4-hydroxypiperidine (268 mg, 2.60 mmol), absolute ethanol (17 ml, 40 vol), activated 3 Å molecular sieves (420 mg), titanium (IV) isopropoxide (1.94 ml, 4.62 vol) and STAB (2.34 g, 11.1 mmol) was reacted in accordance with the general procedure D. The isolated waxy solid was purified by preparative HPLC, eluting with acetonitrile/water/0.1% TFA as a gradient, to give the title compound as a white solid (380 mg, 73%). 1H NMR (400 MHz, CDCl3) δ7.21 (d, 2H), 6.86 (d, 2H), 4.02 (t, 2H), 3.75 (dt, 2H), 3.59-3.47 (m, 2H), 2.63 (t, 2H), 2.53 (br s, 4H), 2.35 (s, 2H), 2.33-2.25 (m, 2H), 2.13-1.96 (m, 6H), 1.93-1.83 (m, 2H), 1.82-1.76 (m, 4H), 1.72-1.59 (m, 3H), 1.47-1.29 (m, 3H).
