実験手順

To a stirred solution of methyl-{4-[4-(3-pyrrolidin-1-ylpropoxy)phenyl]tetrahydropyran-4-ylmethyl}amine (200 mg, 0.60 mmol) and triethylamine (102 μL, 0.72 mmol) in anhydrous dichloromethane (8 mL) under nitrogen atmosphere was added dropwise a solution of acetyl chloride (52 μL, 0.72 mmol) in anhydrous dichloromethane (2 mL). After stirring overnight, the reaction mixture was quenched with a saturated aqueous solution of NaHCO3. The organic layer was separated and washed with water then dried over magnesium sulfate, filtered, concentrated under reduced pressure and purified by column chromatography on silica gel eluting with DCM:MeOH (95:5 to 90:10) to give the title compound (86 mg, 36%). 1H NMR (400 MHz, CDCl3) δ Shows rotomers 7.19-7.13 (2d, 2H), 6.91-6.88 (d, 2H), 4.05-4.02 (m, 2H), 3.85-3.80 (m, 2H), 3.56-3.45 (m, 4H), 2.67-2.65 (m, 2H), 2.60-2.56 (m, 4H), 2.32-1.96 (several multiplets, 12H).
