실험 절차

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-bromophenyl)-4-fluoro-1-methylpiperidine (133 mg, 0.49 mmol). The reaction was then allowed to cool to room temperature 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 title compound as a brown solid (281 mg, used without further purification). 1H NMR (400 MHz, MeOD) δ 7.76 (d, J=7.7 Hz, 2H), 7.41 (d, J=7.8 Hz, 2H), 2.94-2.91 (m, 2H), 2.59 (t, J=12.0 Hz, 2H), 2.45 (s, 3H), 2.30-2.22 (m, 1H), 2.20-2.12 (m, 1H), 2.01-1.95 (m, 2H); 19F NMR (400 MHz, MeOD) δ—162.38; MS ESI 320.1 [M+H]+, calcd for [C18H27BFNO2+H]+ 320.21.
