99% | With sodium dithionite In water at 50℃; for 2 h; | Sodium DITHIONITE (89percent, 81.4 kg) was added to a stirred slurry of 4-methoxy- 5-(3-MORPHOLINOPROPOXY)-2-NITROBENZONITRILE (48.8 kg) in water (867 litres) and the resultant mixture was heated to 50°C for approximately 2 hours to complete the reaction. The temperature of the reaction mixture was raised to approximately 70°C and a concentrated aqueous hydrochloric acid solution (36percent, 270 kg) was added over 3 hours. The resultant mixture was cooled to 20-25°C and sodium hydroxide liquor (47percent, 303.7 kg) was added whilst stirring of the reaction mixture was continued. The reaction mixture was extracted with two portions of methylene chloride (1082 kg and 541 kg respectively) and the combined organic extracts were washed with water (510 litres). The organic phase was evaporated to give 2- AMINO-4-METHOXY-5- (3-MORPHOLINOPROPOXY) benzonitrile (46.3 kg, 99percent yield); mp. 87. 5°C ; NMR Spectrum: (DMSOd6) 1.79 (M, 2H), 2.36 (t, 4H), 2.36 (t, 2H), 3.56 (t, 4H), 3.73 (s, 3H), 3. 86 (t, 2H), 5.66 (br s, 2H), 6.4 (s, 1H), 6.89 (s, 1H) ; Mass Spectrum : M+H+ 292. |

Sodium dithionite (89percent, 81.4 kg) was added to a stirred slurry of 4-methoxy- [5- (3-MORPHOLINOPROPOXY)-2-NITROBENZONITRILE] (48.8 kg) in water (867 litres) and the resultant mixture was heated to [50°C] for approximately 2 hours to complete the reaction. The temperature of the reaction mixture was raised to approximately [70°C] and a concentrated aqueous hydrochloric acid solution (36percent, 270 kg) was added over 3 hours. The resultant mixture was cooled to [20-25°C] and sodium hydroxide liquor (47percent, 303.7 kg) was added whilst stirring of the reaction mixture was continued. The reaction mixture was extracted with two portions of methylene chloride (1082 kg and 541 kg respectively) and the combined organic extracts were washed with water (510 litres). The organic phase was concentrated by distillation to remove 800 litres of solvent. There was thus obtained a methylene chloride solution (503.5 kg) containing 2-amino-4-methoxy-5- (3-morpholinopropoxy) benzonitrile (46.3 kg, 99percent yield) suitable for use in the next stage. [A portion of the [2-AMINO-4-METHOXY-5- (3-MORPHOLINOPROPOXY)] benzonitrile was isolated using the following procedure:- A sample of the methylene chloride solution was evaporated. There was thus obtained [2-AMINO-4-METHOXY-5- (3-MORPHOLINOPROPOXY)] benzonitrile as a solid, m. p. 87.
