2-formyl-N,N-dimethylbenzamide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2-formylbenzoic acid (500 mg, 3.33 mmol), N,N-diisopropylethylamine (0.58 mL, 3.3 mmol), and dimethylamine/ethanol solution (1.2 mL, 5.6 M, 6.7 mmol) in 3.3 mL of dichloromethane was added 1-ethyl-3-(3-dimethylaminopropyl)-3-ethylcarbodiimide monohydrochloride (1.28 g, 6.67 mmol) at 0° C. After being stirred at room temperature overnight, the reaction mixture was diluted with diethyl ether. The solution was washed with 1N HCl, saturated NaHCO3 aqueous solution, brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo to obtain the title compound as a slightly yellow oil (113 mg, 19%). The solution was washed with 1N HCl, saturated NaHCO3 aqueous solution, brine dried over MgSO4 After filtration the filtrate was concentrated in vacuo

The solution was washed with 1N HCl, saturated NaHCO3 aqueous solution, brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo to obtain the title compound as a pale yellow oil (113 mg, 19%). The solution was washed with 1N HCl, saturated NaHCO3 aqueous solution, brine dried over MgSO4 After filtration the filtrate was concentrated in vacuo
