72% | With sodium hydroxide; In (2S)-N-methyl-1-phenylpropan-2-amine hydrate; dichloromethane; water; | Step 1 Preparation of (Z)-3-(3-nitro-4-methoxyphenyl)-2-(3,4,5-trimethoxyphenyl)-prop-2-ene-nitrile 3.0 g of 3-nitro-4-methoxybenzaldehyde, 3.4 g of <strong>[13338-63-1]3,4,5-trimethoxyphenylacetonitrile</strong>, 800 mg of sodium hydroxide and 100 mg of octylmethylammonium chloride were dissolved in 15 ml of water and 15 ml of dichloromethane and reacted for 4 hours at room temperature. Ice water was added to the reaction liquid, which was then extracted three times each with dichloromethane. The extract was dried with anhydrous sodium sulfate and concentrated. The concentrated liquid was purified by crystallization (ethyl acetate) to obtain 4.4 g of the intended compound. The yield was 72%. 1 H-NMR(CDCl3): 8.30 (1H, dd, J=2.4, J=9.0), 8.21 (1H, d, J=2.4), 7.38 (1H, s), 7.21 (1H, d, J=9.0), 6.86 (2H, s), 4.05 (3H, s), 3.94 (6H, s), 3.89 (3H, s); mass spectrum (m/z): 370 (M+); melting point 191-192 C. |

The mixture was stirred vigorously for 3 hours at room temperature. The ice water was added to the mixture and the mixture was extracted with dichloromethane three times and dried over anhydrous sodium sulfate. The organic layer was concentrated and the residue was crystallized from ethyl acetate to give 4.9 g of the intended compound. The yield was 48.5%. 1 H-NMR(CDCl3): 8.23 (1H, J=2.1), 8.15 (1H, dd, J=2.1, 8.4), 7.67 (1H, d, J=8.4), 7.41 (1H, s), 6.88 (2H, s), 3.94 (6H, s), 3.91 (3H, s), mass spectrum (m/z): 374 (M+); melting point 198-199 C. |

The mixture was stirred vigorously for 3 hours at room temperature. The ice water was added to the mixture and the mixture was extracted with dichloromethane three times and dried over anhydrous sodium sulfate. The organic layer was concentrated and the residue was purified by silica gel column chromatography (dichloromethane) to give 1.5 g of the intended compound. The yield was 14.1%. 1 H-NMR(CDCl3): 8.35 (1H, J=1.5), 8.18 (1H, dd, J=1.5, 8.1), 7.47 (1H, d, J=8.1), 7.44 (1H, s), 6.88 (2H, s), 3.95 (6H, s), 3.90 (3H, s), 2.67 (3H, s); mass spectrum (m/z): 354 (M+); melting point 162-163 C. |

With sodium methylate; In methanol; for 3h;Reflux; | [0149] A mixture of benzo[b]thiophene-2-carbaldehyde (1.62 g; 0.01 mol) and 2-(3,4,5-trimethoxyphenyl) acetonitrile (2.07 g; 0.01 mol), sodium methoxide (2.5 gm) in methanol (50 ml) were stirred at reflux temperature for 3 hours. The reaction mass was cooled to room temperature, and crushed ice was added to get solid product. The crude solid was separated by filtration and washed several times with cold methanol (3X 5 ml). The isolated yellow solid recrystallized from methanol gave (Z)-3- (benzo[b]thiophen-2-yl)-2-(3,4,5-trimethoxyphenyl) acrylonitrile as a yellow crystalline product. |
