실험 절차

6-Phenylhexanoic acid (0.150 g, 0.78 mmol) and CDI (0.253 g, 1.56 mmol) were added together and then reacted with nitrohexane (0.153 g, 1.17 mmol) and DBU (0.297 g, 1.95 mmol) according to the general procedure. Purification by column chromatography gave 0.090 g (38%) as a yellow oil: 1H NMR (400 MHz, CDCl3) δ 7.28 (m, 2H), 7.17 (m, 3H), 5.11 (dd, J=4.8, 10.4 Hz, 1H), 2.61 (m, 4H), 1.63 (m, 6H), 1.33 (m, 8H) 0.90 (t, J=6.8 Hz, 3H) ppm; 13C NMR (100 MHz, CDCl3) δ 199.5, 142.5, 128.6, 128.5, 126.0, 94.6, 39.5, 35.9, 31.3, 31.2, 29.9, 28.7, 25.7, 23.3, 22.4, 14.1 ppm; IR νmax (cm−1) 3027, 2930, 2858, 1731, 1559, 1454, 1363, 1030, 748, 699; HRMS (FAB) calcd for C18H27NO3 (MNa+) 328.1883, found 328.1881.
