The resulting mixture was stirred at room temperature for an appropriate time (Table 2). After completion of the reaction as monitored by TLC, the reaction mixture was diluted with toluene (10 mL) and water (6 mL). The aqueous layer which contained the product was separated from theorganic layer and evaporated under reduced pressure toleave the product. The products were characterized on the basis of their melting points, elemental analysis and IR, 1HNMR and 13C NMR spectral analysis. |

The temperature was increased to 25 °C and the reaction continued. After completion of the reaction (monitored by TLC), the solvent was evaporated and MeCN (2 mL) was added. The mixture was cooled to 0 °C and filtered to remove the trichloroacetamide by-product. The filtrate was then concentrated under reduced pressure and purified by column chromatography. The products were identified by comparing their physical and spectral data with those of authentic samples reported in the literature. |
