Used Chemicals


To a solution of 3-phenylpropionic Acid (1.80 g, 12.0 mmol) and 2-phenylethylamine (1.60 g, 13.2 mmol) in MeOH (120 mL) was added DMTMM (3.65 g, 13.2 mmol) and the mixture was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure. Saturated aqueous sodium bicarbonate solution (100 mL) was added to the residue. After being stirred for 10 minutes, the mixture was extracted with diethyl ether (100 mL). The separated organic layer was washed with deionized water (50 mL), 1 mol/L hydrochloric acid (50 mL), deionized water (50 mL) and brine (100 mL), dried over magnesium sulfate and filtered. The solvent was removed under reduced pressure and the residue was purified by column chromatography (2:1 ethyl acetate / hexane on SiO2), giving white solid (2.54 g, 84%).

Experimenter’s Comments

The reaction mixture was monitored by TLC (hexane : ethyl acetate = 1 : 1, Rf = 0.30) and GC.

Formation of Amides by Condensation of Carboxylic Acids and Amines in Alcohols or Water

Experimental procedure2): DMTMM (182.6 mg, 0.66 mmol) is added to a mixture of 3-phenylpropionic acid (90.1 mg, 0.6 mmmol) and 2-phenylethylamine (80.0 mg, 0.66 mmol) in CH3OH (6.0 mL) at room temperature. After 3 h with stirring at room temperature, the CH3OH is evaporated. The resulting residue is dissolved in ether, and washed successively with saturated sodium carbonate, water, 1 mol/L HCl, water and brine and dried over MgSO4. The crude product is purified by preparative TLC (hexane :EtOAc = 1:2) to give 148.8 mg of 1 (98%)as a colorless crystals.
