General Remarks1 H NMR spectra were recorded at 300 or 400 MHz with CDCl3 as solvent. 13 C-NMR spectra were obtained at 75.4 or 100.59 MHz in CDCl 3 . Chemical shifts were determined relative to the residual solvent peaks (CHCl3, δ = 7.26 ppm for hydrogen atoms, δ = 77.0 for carbon atoms).

One-Pot Esterification and Amide Formation via Acid-Catalyzed Dehydration and Ritter Reactions. -Nearly quantitative conversion of carboxylic acids to ester is achieved using acetonitrile as a water trap. Substrates having a nitrile group suffer an intramolecular dehydration and rehydration furnishing amido esters in the absence of MeCN. -(DAWAR, P.; RAJU, M. B.; RAMAKRISHNA*, R. A.; Synth.
