Pyridine sulfur trioxide (6.4 g, 0.040 moles) was added to the mixture, the mixture was stirred for 30 minutes, and was then washed with water (500 mL). The organic layers were then concentrated by distillation until 600 mL of solvent was removed, and ethyl acetate (500 mL) was added. Oxalic acid dihydrate (27.2 g, 0.216 moles) was then added. The resulting suspension was stirred for 16 hours and filtered to yield the product as a white solid. The resulting product was slurried in additional ethyl acetate (200 mL), filtered and dried under vacuum to yield 63.3 g of the product as a white solid (0.158 moles, Yield: 59percent).

Example 6Preparation of (S)-N-methyl-(3-(1-naphthyloxy)-3-thien-2-yl) Propylamine Hydrochloride (Duloxetine Hydrochloride)Sodium hydroxide (0.324 kg, 8.1 moles, 2 eq), potassium carbonate (126 kg, 9.1 moles, 2.25 eq.) and (S)-3-dimethylamino-1-(2-thienyl)-1-propanol (750 g, 4.05 moles), were heated in DMSO (7.5 L) at 80° C. for 3 hours and cooled to 40° C. 1-fluoronaphthalene (770'gi.5.3 mol, 1.3 eq) was then added over 5 minutes. Next, the mixture was heated at 40° C. for 17 hour and then at 50-60° C. for 40 hours. The molar ratio of product (Compound IV) to staring alcohol (Compound S-II) was 85.3:14.7, and Compound IV was 92percent ee as determined by HPLC of an aliquot. The mixture was then cooled to 20° C. and quenched with water (5 L). The mixture was divided in two and each portion was extracted twice with isopropyl acetate (2.x.2 L). The four organic phases were combined, washed with water (5 L), and pyridine sulphur trioxide complex (110 g, 0.69 moles, 0.17 eq.) was added. The mixture was then stirred at 20° C. for 30 minutes, and washed with water (5 L). Oxalic acid dihydrate (0.38 kg, 3.0 moles, 0.75 eq.) was then added, and the mixture stirred at 15-20° C. for 16 hours. The mixture was then filtered and slurried in acetone (2.5 L) and isopropyl acetate (5 L) for one hour, and then filtered to yield 2.1 kg (wet product) of (S)-N,N-dimethyl-3-(1-naphthyloxy)-3-thien-2-yl)propylamine oxalic acid salt as an off-white solid (Yield: 75percent; equivalent to 1.21 kg, (dry product)). The molar ratio of product (Compound IV) to starting alcohol (Compound S-II) was 98.7:1.3 as determined by HPLC. Compound IV oxalate salt was 92percent ee as determined by chiral HPLC.Example 7Preparation of (S)-N,N-dimethyl-(3-(1-naphthyloxy)-3-thien-2 yl)propylamine Oxalic Acid SaltSodium hydroxide (8.635 g, 216 mmol, 2 eq), potassium carbonate (33.565 g, 243 mmol, 2.25 eq.) and (S)-3-dimethylamino-1-(2-thienyl)-1-propanol (20 g, 108 mmol), were heated in DMSO (200 mL) at 80° C. (temperature inside flask) under vacuum such that approximately 100 mL of DMSO were distilled in 1 hour. An additional 100 mL of DMSO were then added, and the mixture heated at 80° C. for a further 2 hours. Thereafter, the mixture was cooled to 40° C. and stirred under an atmosphere of nitrogen. 1-Fluoronaphthalene (17.35 g, 119 mmol, 1.1 eq) was then added, and the mixture maintained with stirring at 40° C. Samples were taken periodically and analysed by NMR. Once an approximately 92percent conversion had been achieved (24 hours), as determined by the ratio of Compounds IV and S-II in the 1H-NMR spectrum, the mixture was cooled to 25° C., quenched with water (150 mL) and extracted twice with isopropyl acetate (2.x.100 mL). The two organic phases were combined, washed with water (75 mL), and pyridine sulphur trioxide complex (1.72 g, 10.8 mmol, 0.1 eq.) was added. The mixture was then stirred at 20° C. for 60 minutes and washed with water (150 mL). The aqueous layer was analysed to be pH 6.8. Oxalic acid dihydrate (10.9 g, 86 mmol, 0.8 eq.) was then added, and the mixture stirred at 15-20° C. for 16 hours. The mixture was then filtered and homogenized to yield 41.83 g of (S)-N,N-dimethyl(3-(1-naphthyloxy)-3-thien-2 yl)propylamine oxalic acid salt as an off-white solid (Loss on drying: 6.94percent, Titration: 98.1percent, Karl Fischer: 0.06percent). |

Suspension is stirred and in few portions 2 g of (s)-3-(dimethylamino)-1-(thienyl)-propan-1-ol is added. After the addition is completed the suspension is warmed up to 70°C. 1.27 ml of 1-fluoronaphthalene is added and the reaction mixture is heated to 110°C. At this temperature the solution is stirred for another three hours. Then the reaction solution is dissolved with 300 ml of water and extracted twice with 100 ml ether. Combined ether phases are rinsed with water, dried with sodium sulphate end evaporated to dryness. Obtained oil is dissolved in 50 ml ethyl acetate and 0.9 g of oxalic acid is added. The suspension is further stirred for one hour, filtered off the product and washed with ethyl acetate. The product is dried to obtain 3.5 g (80 percent) of (S)-N,N-dimethyl-3-(1-naphthalenyloxy)-3-(2-thienyl)propanamine oxalate. |
