Procedure
To a stirred solution of {4-[4-(3-pyrrolidin-1-ylpropoxy)phenyl]tetrahydropyran-4-yl}methylamine (200 mg, 0.63 mmol) and triethylamine (106 μL, 0.754 mmol) in anhydrous dichloromethane (9 mL) under nitrogen atmosphere was added dropwise a solution of dimethylcarbamoylchloride (69 μL, 0.754 mmol) in anhydrous dichloromethane (1 mL). After stirring for 3 h at 0° C., 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 (80 mg, 32%). 1H NMR (400 MHz, CDCl3) δ7.13 (d, 2H), 6.86 (d, 2H), 3.98 (t, 2H), 3.84 (t, 1H), 3.74 (m, 2H), 3.52 (m, 2H), 3.36 (d, 2H), 2.69 (s, 6H), 2.65 (m, 2H), 2.57 (m, 4H), 2.02-1.95 (m, 4H), 1.84-1.78 (m, 6H).
