48.5% | With sodium hydroxide; In (2S)-N-methyl-1-phenylpropan-2-amine hydrate; dichloromethane; water; | Step 1 Preparation of (Z)-3-(3-nitro-4-chlorophenyl)-2-(3,4,5-trimethoxyphenyl)-prop-2-ene-nitrile 5.0 g of 3-nitro-4-chlorobenzaldehyde, 5.6 g of <strong>[13338-63-1]3,4,5-trimethoxyphenylacetonitrile</strong>, 1.3 g of sodium hydroxide and 500 mg of trioctylmethylammonium chloride were dissolved in 10 ml of water and 50 ml of dichloromethane. 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. |

85% | With potassium fluoride;AlCl3; | EXAMPLE 1 A mixture of 87 g (1.5 mol) of potassium fluoride and 250 g of tetramethylene sulphone in a glass reaction vessel was subjected to incipient distillation for the removal of water until 25 g of tetramethylene sulphone had passed over. 192 g of 3,4-dichloro-nitrobenzene, 10 g (0.025 mol) of methyl -trioctyl-ammonium chloride and 1.65 g (0.0125 mol) of AlCl3 were then added and the was 97% (determined by gas chromatography). The reaction mixture was then worked up by distillation. 149 g of 3-chloro-4-fluoro-nitrobenzene having a boiling point of 92-93 C. at 10 mbar were obtained. This corresponds to a yield of 85% of theory. |

Example 1 Red Complex from Reactive Red 120, 3-(2-Ethylhexyloxyl)Propylamine and Aliquat 336 (0102) 14.7 gram of Reactive Red 120 (50% dye content), 2.81 gram of 3-(2-ethylhexyloxy)-propyl amine, 0.84 gram of sodium bicarbonate and 30 mL of water were charged into a reactor equipped with agitator, temperature control and condenser. The mixture was heated to 80 C. for several hours until the starting material Reactive Red 120 was gone as monitored by TLC. Then 12.1 gram of Aliquat 336 was added slowly and stirred at 80 C. for one hour. The reaction mixture was cooled to room temperature and dark red solid was precipitated. The solid was filtered and washed with water to remove salts. 24.1 gram of red solid with color value of 12.8 was obtained. |
