Procedure
(S)-2-(1-acetyl-6-(1-cyclopropyl-1H-pyrazol-4-yl)-2-methyl-1,2,3,4-tetrahydroquinolin-5-yloxy)benzonitrile was synthesized according to the procedures described above for Example 36, with the following changes: (1) in Step 2, 1-cyclopropyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole was used in place of tert-butyl 4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)piperidine-1-carboxylate (3) Step 3 (removal of the Boc-protecting group) was eliminated. 1H NMR (300 MHz, CD3OD) δ ppm 0.92-1.05 (m, 4H), 1.16 (d, J=6.30 Hz, 3H), 1.35-1.52 (m, 1H), 2.10-2.40 (m, 5H), 2.58-2.80 (m, 1H), 3.55-3.65 (m, 1H), 4.68-4.8 9 (m, 1H), 6.40-6.55 (m, 1H), 7.05-7.15 (m, 1H), 7.30-7.52 (m, 2H), 7.55-7.65 (m, 1H), 7.70-7.80 (m, 2H), 7.96 (s, 1H). MS (ESI, pos. ion) m/z 413 [M+H]+.
