(1S)-1-氨基-1,3,4,5-四氢-3-甲基-2H-3-苯并氮杂卓-2-酮

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: (S)-1-Amino-3-methyl-2,3,4,5-tetrahydro-1H-3-benzazepin-2-one di-p-toluoyl-L-tartaric acid salt (11.83 g, 20.5 mmol) was dissolved in 45 mL of aqueous 1.0 N sodium hydroxide solution and extracted with methylene chloride (3×25 mL). The combined methylene chloride layers were washed with 35 mL aqueous 1.0 N sodium hydroxide solution, then brine solution, and dried over anhydrous MgSO4. Removal of solvent under vacuum gave the title compound (3.38 g) as a colorless oil (87% yield, 93.2% ee). extracted with methylene chloride (3×25 mL) The combined methylene chloride layers were washed with 35 mL aqueous 1.0 N sodium hydroxide solution brine solution, and dried over anhydrous MgSO4 Removal of solvent under vacuum
