YieldReaction ConditionsOperation in experiment
36.6% With triethylamine; In dichloromethane; at -15 - 20℃;Product distribution / selectivity; Example 3Synthesis of prasugrel by coupling thiophene acetate Al hydrochloride with the bromide CI2.00 g Thiophene acetate Al hydrochloride (Example 2) and 2.75 g bromide compound CI, were suspended in25 ml dichloromethane (dried over CaCl2). The suspension was cooled to -15/-10C,1.73 g triethylamine was added dropwise over 5 minutes. The yellow suspension was kept at -10C for 1 hour and was then allowed to slowly warm to 0-5C. Reaction progress was monitored with HPLC. After 4 hours 20 minutes, the reaction mixture was allowed to warm to ambient temperature. After 5.5 hours, the obtained dark brown suspension was washed with2x25 ml water, dried (Na2S04) and concentrated in vacuo.[0051] The obtained oil was filtered over silica 60 (63-200 mueta , 10 g) using toluene/ethyl acetate 20/1 (v/v) as eluens. The filtrate was concentrated in vacuo. To the obtained oil,20 ml isopropyl ether was added. The suspension was stirred over night at ambient temperature. The solid was isolated by filtration and dried at air.Isolated yield: 1.17 g (36.6%), off-white/bit yellowish solidHPLC: 98.4% purity
With N-ethyl-N,N-diisopropylamine; In dichloromethane; at 25 - 30℃; for 2 - 3h;Product distribution / selectivity; EXAMPLE 10: PREPARATION OF 2-ACETOXY-5-(A-CYCLOPROPYL CARBONYL-2-FLUOROBENZYL)-4,5,6,7-TETRAHYDROTHIENO[3,2- C]PYRIDINE (FORMULA I).Acetic acid 4,5,6,7-tetrahydro-thieno[3,2-c]pyhdin-2-yl ester hydrochloride (54.0 g), dichloromethane (750 mL) and diisopropylethylamine (94.6 mL) are charged into a round bottom flask. A solution of 2-fluoro-alpha-cyclopropylcarbonyl bromide (68.0 g of 2-fluoro-alpha-cyclopropylcarbonyl bromide in 250 mL of dichloromethane) is added to the reaction mixture dropwise at a temperature of 25 0C to 30 0C and maintained at that temperature for 2 to 3 hours. Water (500 mL) is added to the reaction mixture and layers are separated. Organic layer is washed with water (3*100 mL) and then dried over sodium sulfate followed by <n="45"/>evaporation under reduced pressure at a temperature of 35 0C to 45 0C. The resulting residue is subjected to silica gel column chromatography, using a 20:80 mixture of ethyl acetate and hexane by volume as the eluent, to give a yellow oil. Diisopropyl ether (200 ml_) is added to the obtained oil and stirred for 10 minutes at a temperature of 25 0C to 35 0C. The obtained suspension is filtered and the solid is dried at a temperature of 50 0C to 55 0C for 1 to 2 hours to afford the title compound (9.0 g).Purity: 74% by HPLC.
