실험 절차
1-(1-Hydroxy-1-methoxycarbonylmethyl)-3-(triphenylmethylamino)-4-(3-phenylprop-2-ynylthio)azetidin-2-one (395mg) was dissolved in a 1:1 mixture of dry tetrahydrofuran and dioxan (14ml) and the solution, under nitrogen, was cooled to -10°. Pyridine (176mg) in dry dioxan (1ml) was then added, followed by the dropwise addition of thionyl chloride (0.153ml) in dry dioxan (4ml) over 2-3 minutes. After a further 15 minutes the precipitated solid was filtered off and the filtrate evaporated to dryness. Dry toluene was added and was decanted from any solid. The organic solution was evaporated to give 1-(1-Chloro-1-methoxycarbonylmethyl)-3-(triphenylmethylamino)-4-(3-phenylprop-2-ynylthio)azetidin-2-one as an amorphous solid (419mg), after drying overnight in vacuo.
