YieldReaction ConditionsOperation in experiment
With 4-methyl-morpholine; diphenylphosphoranyl azide; hydrogen; copper(I) iodide; benzyl alcohol;palladium; In methanol; 1,2-dichloro-ethane; Example 16A 2,6-Dimethoxyaniline To a stirred solution of 2,6-dimethoxybenzoic acid (2.00 g, 11.0 mmol) in 1,2-dichloroethane (45 mL) at ambient temperature was successively added N-methylmorpholine (1.45 mL, 13.2 mmol) and diphenylphosphoryl azide (2,60 mL, 12.1 mmol). After heating the mixture for 2 hours at 75 C., cuprous iodide (150 mg) and benzyl alcohol (2.27 mL, 22.0 mmol) were added and heating was continued overnight. Solvents were removed in vacuo and the residue was chromatographed on silica gel, eluding with 4:1 hexane-ethyl acetate to give the intermediate carbamate (1.50 g, 48 % yield) as a white, crystalline solid. The solid was dissolved in methanol (15 mL) and added to a flask purged with nitrogen containing 10% palladium-on-charcoal (500 mg). The mixture was placed under a balloon of hydrogen and stirred 4 hours at ambient temperature. The mixture was filtered through a pad of Celite and solvents were removed in vacuo to give the title compound (800 mg, 48% yield).

YieldReaction ConditionsOperation in experiment
84.5% Synthesis of Compound (1) (S)-(-)-N-[(1-Ethyl-2-pyrrolidinyl)methyl]-2,6-dimethoxybenzamide Take 2.8 g (15.4 mmol) 2,6-dimethoxybenzoic acid and add with 20 mL hexane and 2.4 mL (33.3 mmol) thionyl chloride. Heat and reflux for 2 hours and evaporate all volatile substances under reduced pressure. Then dissolve the residue in methylene chloride (20 mL) and slowly drop 20 mL methylene chloride containing 2.0 g (15.6 mmol) (S)-(-)-2-aminomethyl-1-ethylpyrrolidine into the methylene chloride solution. Stir the solution at room temperature overnight. Next wash the reaction solution with saturated sodium bicarbonate aqueous solution (40 mL) and the reaction solution separates into two phases. The organic phase is dried by anhydrous sodium sulfate (Na2SO4) and then is concentrated under reduced pressure. The residue is separated and purified by liquid chromatography (silicon dioxide(SiO2), dichloromethane(CH2Cl2): methanol(CH3OH)=100:15) to get colorless solid product, the compound (1) (3.8 g, 84.5%).

80% General procedure: Benzoic acid derivatives (1 mmol) and heterogeneous catalyst (10 mg) were mixed for 5 min in 1 mL of anhydrous toluene. Then, the amine (1.2 mmol) was added and the mixture was reacted under ultrasound for about 15-60 min at room temperature. After completion of the reaction (monitored by TLC), the catalyst was separated through filtration and the solvent was removed in vacuo. The obtained residue was dissolved in chloroform (10 ml) and washed with 10% NaHCO3 (10 ml) and HCl (1 M, 10 ml). The organic layer was extracted and dried over Na2SO4 and concentrated under reduced pressure to afford the amide, which was purified by recrystallization or column chromatography.
