実験手順

4-[4-(3-Pyrrolidin-1-ylpropoxy)phenyl]tetrahydro-2H-pyran-4-carbaldehyde (317 mg, 1 mmol), piperazine-1-carboxylic acid amide hydrochloride (273 mg, 1.65 mmol), absolute ethanol (12.7 ml), activated 3 Å molecular sieves (320 mg), Et3N (0.278 ml), titanium (IV) isopropoxide (1.46 ml, 5.20 mmol) and STAB (1.8 g, 8.5 mmol) were reacted in accordance with the general procedure D. The isolated crude product was purified by column chromatography on silica eluting with DCM:MeOH:NH3 (98:1:1) to give the title compound as a off white solid (70 mg, 16%). 1H NMR (400 MHz, CDCl3) δ 7.21 (d, 2H), 6.86 (d, 2H), 4.30 (br s, 2H), 4.02 (t, 2H), 3.80-3.71 (m, 2H), 3.58-3.48 (m, 2H), 3.23-3.15 (m, 4H), 2.63 (t, 2H), 2.53 (br s, 4H), 2.40 (s, 2H), 2.19-1.73 (m, 14H).
