The title compound was prepared by the Suzuki coupling procedure of Example 35, step (b) using 4-nitrophenylboronic acid (167 mg, 1.00 mmol) and 4-trifluoromethanesulfonyloxy-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (as prepared in Example 13, step (a), 295 mg, 1.00 mmol). Silica gel chromatography (10% EtOAc in hexanes) afforded the title compound (273 mg, 90%) as an oil. 1H-NMR (CDCl3; 400 MHz): δ 8.19 (d, 2H, J=8.8 Hz), 7.50 (d, 2H, J=8.8 Hz), 6.23 (m, 1H), 4.12 (m, 2H), 3.66 (m, 2H), 2.54 (m, 2H), 1.49 (s, 9H).
