WebTreatment of 6 with SnCl2 in refluxing ethanol reproducibly gave a single product in nearly quantitative yield. However the product was not an aniline or an amidine, as expected from the results obtained from 2b. NMR spectral data show incorporation of an ethoxy group and the presence of an ester carbonyl and an exchangeable hydrogen.
