Procedure
The title compound was prepared using a procedure analogous to 4-(2,3-dimethylphenoxy)-1-(5-(4-(hydroxymethyl)phenyl)-3,4-dihydroquinolin-1(2H)-yl)butan-1-one except that 4-(hydroxymethyl)phenylboronic acid was replaced by 1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl)piperazine. LCMS, [M+H]+=485.3. 1H NMR (400 MHz, CDCl3) δ 8.21 (d, J=5.1 Hz, 1H), 7.22-7.28 (m, 2H), 7.07-7.13 (m, 1H), 7.03 (t, J=7.9 Hz, 1H), 6.76 (d, J=7.5 Hz, 1H), 6.67 (d, J=8.1 Hz, 1H), 6.53 (s, 1H), 6.50 (d, J=5.9 Hz, 1H), 3.98 (t, J=5.7 Hz, 2H), 3.80 (t, J=6.9 Hz, 2H), 3.47-3.59 (m, 4H), 2.95-3.04 (m, 4H), 2.77 (t, J=7.3 Hz, 2H), 2.53 (t, J=6.5 Hz, 2H), 2.16-2.27 (m, 5H), 2.00 (br. s, 3H), 1.85 (quin, J=6.7 Hz, 2H).
