Melting points were taken on a Mel-Temp apparatus and are uncorrected. Proton nmr spectra were obtained on a Hitachi R-20A spectrometer in carbon tetrachloride with tetramethylsilane as internal reference. Infrared spectra were taken with a Perkin-Elmer 237B spectrophotometer. Elementary analyses were performed by Chemalytics Inc., Tempe, Arizona.
