Materials and Methods. The NMR spectra were recorded on a Varian EM-360 and/or The University of Chicago 500-MHz spectrometer with tetramethylsilane as an internal standard in CDC13. Melting points are unconeded. All new compounds gave satisfactory analyses for C and H within f0. 3% and/or mms spectra consistent with the assigned structures. NJV- Diethyl-1-naphthamide was prepared as previously described." THF was distilled from ...
