実験手順

The title compound was synthesized according to the method described for the synthesis of 1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperidin-4-yl acetate, except substituting 4-(4-bromophenoxy)-1-methylpiperidine (300 mg, 1.11 mmol). The reaction was then allowed to cool to rt and was diluted with EtOAc and water was added. The resulting mixture was extracted with EtOAc and the combined organic extracts were washed with brine, dried over MgSO4 and concentrated to give the crude product. Crude product was purified by flash chromatography using MeOH/CH2Cl2 (2:98 to 15:85) to give the title compound as a brown solid (200 mg, 57%). 1H NMR (400 MHz, CD3OD) δ 7.68 (d, J=7.6 Hz, 2H), 6.94 (d, J=7.7 Hz, 2H), 4.53 (br s, 1H), 2.94-2.91 (m, 2H), 2.58-2.50 (m, 2H), 2.40 (s, 3H), 2.18-2.00 (m, 2H), 1.93-1.78 (m, 2H), 1.34 (m, 12H); MS ESI 318.1 [M+H]+, calcd for [C18H28BNO3+H]+ 318.22.
