Procedure

The title compound was synthesized according to the synthesis of 4-(4-isopropylpiperazin-1-yl)phenylboronic acid, except substituting 4-(1-(4-bromophenyl)piperidin-4-yl)morpholine (250 mg, 0.77 mmol). The aqueous layer was washed with EtOAc and concentrated. The residue was triturated with THF and the filtrate was concentrated to give the title compound as a yellow solid (87 mg, 40%). 1H NMR (400 MHz, MeOD) δ 7.58 (br s, 2H), 6.93 (d, J=7.5 Hz, 2H), 3.85-3.82 (m, 2H), 3.72 (br s, 4H), 2.72 (t, J=12.3 Hz, 2H), 2.63 (br s, 4H), 2.40-2.34 (m, 1H), 2.01-1.98 (m, 2H), 1.62-1.54 (m, 2H); MS ESI 291.1 [M+H]+, calcd for [C15H23BN2O3+H]+ 291.18.
