27. 3, N=0.50-0.67, [5 mmol], was added and the reaction mixture was stirred for 5 min at room temperature. All additions were carried out in an inert atmosphere glove box. The reactions were quenched using 6 M HCl under cold conditions. The resultant solution was extracted using ethyl acetate (3×10 ml). The combined organic extracts were dried using anhydrous sodium sulphate, evaporated under reduced pressure and assayed on GC. The crude products were chromatographed using silica gel column chromatography to yield pure compounds that were characterised by IR, NMR, MS and physical constants.
28. GC-MS analysis was performed using a Shimadzu, QP-5050 instrument equipped with a hp-5 column. The detector temperature was set at 300°C. The column was programmed initially at 60°C for 5 min and then with a gradient of 10°C/min to 250°C.
