A mixture of l-chloro-4-nitrobenzene (23) (2.37 g, 15.0 mmol), alcohol 22 (1.94 g, 15.0 mmol), and DMSO (25 mL) was treated portionwise with NaH (60% in mineral oil, 660 mg, 16.5 mmol) at 40 0C. The mixture was stirred at 70 0C for 3 h, poured into water (15O mL), and extracted with Et2O (5 x 10O mL). The combined organic fractions were washed with water (250 mL) and brine (250 mL), dried (MgSQ4), and the solvent was removed in vacuo. The resulting solid was recrystallized from Et2O to give 24 (3.12 g, 83%) as yellow needles. 1H NMR (300 MHz, CDCl3): delta = 1.36-1.56 (m, 2 H, 3-Hax, 5-Hax), 1.75-1.91 (m, 3 H, 3-Heq, 4-H, 5-Heq), 1.98 (dt, J= 11.9, 1.9 Hz, 2 H, 2-Hax, 6-Hax), 2.30 (s, 3 H, NMe), 2.85-2.98 (m, 2 H, 2-Heq, 6-Heq), 3.90 (d, J= 5.8 Hz, 2 H, OCH2), 6.94 (me, 2 H, 2′-H, 6′-H), 8.19 Cm0, 2 H, 3′-H, 5′-H) ppm. – 13C NMR (50.3 MHz, CDCl3): 6 = 28.9 (C-3, C-5), 35.1 (C-4), 46.4 (NMe), 55.3 (C-2, C-6), 73.3 (OCH2), 114.3 (C-21, C-6′), 125.8 (C-3′, C-5′), 141.3 (C-41), 164.1 (C-I’) ppm. -MS (70 eV, EI): m/z (%) = 250 (79) [M]+, 249 (100) [M-H]+. – Ci3H]8N2O3 (250.29): calcd. C 62.38, H 7.25; found C 62.25, H 7.40., 20691-89-8
The synthetic route of 20691-89-8 has been constantly updated, and we look forward to future research findings.
