- After heating for the specified time, the solvent was spin-evaporated in vacuo. The residue was extracted with CHCl3-EtOAc (1:1), washed with brine and dried over anhydrous Na2SO4. The solvent mixture was concentrated under vacuum to afford the crude material
- All the yields reported in this paper are calculated based on the amount of halides
- Satisfactory analytical data (within ± 0.4%) were obtained for all the new compounds described. 1HNMR spectra were recorded in a Varian T-60A spectrometer with tetramethylsilane as internal standard. GLC experiments were carried out in a Hewlett-Packard gas chromatograph model 5730A using the column 10% UCW-982 on DMCS (100–120 mesh)
