H NMR spectra were recorded on a JEOL JNM-ECX 400II spectrometer at 400 MHz in CDCl3 with tetramethylsilane (TMS) as an internal standard. Chemical shirts (δ) are reported in parts per million (ppm). Coupling constants (J) are reported in hertz (Hz). Abbreviations are: s, singlet; d, doublet; t, triplet; m, multiplet. 13 C NMR spectra were recorded on a JEOL JNM-ECX 400II spectrometer at 100 MHz in CDCl3. Chemical shirts (δ) are reported in parts per million (ppm) relative to chloroform peak (77.0 ppm). IR spectra were measured on a JASCO FT/IR-6100 spectrometer.
