実験手順

The title compound was synthesized according to the synthesis of 4-(4-isopropylpiperazin-1-yl)phenylboronic acid, except substituting 1-(4-bromophenyl)-cis-3,5-dimethylpiperazine (300 mg, 1.11 mmol). The reaction was quenched with sat. NH4Cl solution, extracted with EtOAc, dried over MgSO4, filtered, and concentrated to dryness. The title compound was isolated by silica gel chromatography (MeOH/CH2Cl2, 6:94 to 1:4) as a yellow solid (59 mg, 23%). 1H NMR (400 MHz, MeOD) δ 7.59 (d, J=6.2 Hz, 2H), 6.91 (d, J=8.2 Hz, 2H), 3.67-3.63 (m, 2H), 3.09-3.01 (m, 2H), 2.32 (t, J=11.6 Hz, 2H), 1.18 (d, J=6.4 Hz, 6H); MS ESI 235.1 [M+H]+, calcd for [C12H19BN2O2+H]+ 235.15.
