✦ Synopsis

7] Procedure: A mixture of the ester 1 (5 mmol) and the amine 2 (IOmmol) was diluted with acetonitrile in an 8-mL Teflon capsule, which was then stored for 3 d at 8 kbar. After evaporation of the solvent and amine, the residue was dissolved in dichloromethane and extracted with dilute HCI (saturated with ammonium sulfate in the case of water-soluble amides 3). In the case of incomplete reaction, the amide was readily separated by flash chromatography.-For reviews on organic syntheses under high-pressure, including a description of the high-pressure equipment used in this study, see: K.
