Melting points were recorded in a Buchi capillary melting point (R-535) apparatus and are uncorrected. IR spectra were recorded on a Perkin–Elmer FT-IR 240C spectrophotometer. 1H NMR spectra were recorded on Gemini-200 spectrometer with TMS as the internal standard. Mass spectra were recorded on a Finnigan MAT 1020 mass spectrometer operating at 70 ev. All chemicals or reagents were purchased from standard commercial suppliers. |

| 熔点是在Buchi毛细管熔点仪（R-535）上测定的，结果没有进行校正。 红外光谱时在Perkin–Elmer FT-IR 240C 红外光谱仪上测定的； 1H NMR核磁共振谱是在Gemini-200核磁共振仪上测定的，所用的内标物是TMS； 质谱是 在Finnigan MAT 1020 质谱仪上测定的，操作能量是 70 eV; 所有的化学品和试剂都是从标准的商业供货商处购买的。 |
