YieldReaction ConditionsOperation in experiment
With thionyl chloride;N,N-dimethyl-formamide; In toluene; at 80℃; for 2.5h; ii) trans-(+)-(2-Phenyl-cyclopropyl)-methylamine hydrochloride; To a solution of /ra/7s-(+)~2-phenyl-cyclopropanecarboxylic acid (60 mg, 0.37 mmol) in toluene (3 ml_) were added dropwise several drops of dimethylformamide and thionyl chloride (0.403 ml_, 5.55 mmol). After stirring at 80 C for 2.5 h, the reaction mixture was concentrated under vacuum. The resulting residue was dissolved in toluene (2 ml_) again, and the solution was added to liquid ammonia (ca. 10 ml_) at - 78 C. After stirring at -78 C for 30 min and then at room temperature for 30 min, CH2CI2 (10 ml) was added to the mixture at -78 C and the resulting mixture was stirred at room temperature overnight. After addition of EtOAc, the mixture was washed with satd. aqueous NH4CI (x2), dried over Na2SO4 and all volatiles were removed under vacuum. The corresponding amide was isolated as pearl yellow powders and further purified by recrystallization from hexane/EtOAc (45 mg).
With oxalyl dichloride; N,N-dimethyl-formamide; In dichloromethane; at 20℃; for 0.75h; To a solution of (l S,2S)-2-phenyl-cyclopropanecarboxylic acid ( 170 mg, 1.05 mmol) in dichloromethane ( 10 ml ) was added oxallyl dichloride ( 145 mg, 1.2 mmol) followed by a few drops of N, N-dimethylformamide at RT. The reaction mixture was stirred at RT for 45 mins before it was concentrated down and dissolved in dichloromethane (1.5 ml). The solution was added slowly to a solution of (S)-l- (4-bromo-phenyl)-propylamine (250 mg, l.Ommol, HC1 salt) and triethylamine (222 mg, 2.2 mmol) in dichloromethane (10 ml) at 0 C. The resulting reaction mixture was stirred at RT for 1.5h. Water was added and the aqueous layer was extracted by dichloromethane. Organic layer was dried by magnesium sulfate and concentrated. The residue was purified via column chromatography on silica gel to afford (1 S,2S)- 2-phenyl-cyclopropanecarboxylic acid [(S)-l-(4-bromo-phenyl)-propyl]-amide (330 mg, 92%). XH NMR (400 MHz, CHLOROF ORM-d) δ ppm 7.37 (d, J=8.6 Hz, 2 H), 7.15 - 7.23 (m, 2 H), 7.11 (d, J=7.3 Hz, 1 H), 7.08 (d, J=8.3 Hz, 2 H), 6.98 (d, J=7.3 Hz, 2 H), 5.75 (d, J=7.6 Hz, 1 H), 4.77 (q, J=7.5 Hz, 1 H), 2.31 - 2.41 (m, 1 H), 1.65 - 1.81 (m, 2 H), 1.48 - 1.59 (m, 2 H), 1.12 - 1.23 (m, 1 H), 0.82 (t, J=7.4 Hz, 3 H); LRMS ( ESI) (M + 1) = 360.04. Molecular Formula =Ci9H20BrNO.
With oxalyl dichloride; In dichloromethane; at 20℃; for 2.5h; In a dry 100 ml round-bottomed flask was added oxalyl chloride (2.0 ml, 23 mmol) to 8B (0.25 g, 1.5 mmol) in CH2Cl2 at room temperature to give a yellow solution. In 2.5 hours, the reaction was complete. The crude mixture was concentrated in vacuo and residual <n="164"/>PATENT ASKl -5001 -WOTFA was removed azeotropically with toluene 3 times to give the desired product (lS,2S)-2- phenylcyclopropanecarbonyl chloride (8B-1), which was used in the next step without further purification.
