Reaction Conditions:
Stage #1: p-benzyloxybenzaldehyde;nitromethanewith sodium methylate in methanol at 0 - 20; for 0.166667 h;
Stage #2: with hydrogenchloride;water in methanol at 0 - 20; for 0.25 h;
Steps:
1.1.1
Manufacturing Example 1-1-1 1-Benzyloxy-4-((E)-2-nitro-vinyl)-benzene; To a mixture of 4-benzyloxybenzaldehyde (1.0 g, 4.7 mmol) and sodium methoxide (28% methanol solution, 150 μL, 0.74 mmol) and methanol (10 mL) were added nitromethane (330 μL, 6.1 mmol) and sodium methoxide (28% methanol solution, 1.0 mL, 4.9 mmol) at 0° C., which was stirred for 10 minutes at room temperature. The reaction mixture was cooled to 0° C., and 5 N aqueous hydrochloric acid solution (20 mL) was added thereto at the same temperature. The reaction mixture was then stirred for 15 minutes at room temperature. The precipitated solids were filtered to obtain the title compound (1.2 g, 100%).1H-NMR Spectrum (DMSO-d6) δ (ppm): 5.20 (2H, s), 7.10-7.14 (2H, m), 7.32-7.48 (5H, m), 7.82-7.85 (2H, m), 8.12 (2H, dd, J=13.5, 18.2 Hz).
