Reaction Steps
Subsequently, 9.7 g (0.024 mol) of ethyl 2-iodo-4,4,5,5-tetrafluoro-5-bromopentanoate and 2.73 g (0.042 mol) of sodium azide were added to 40 ml of 80% ethanol and were refluxed while under stirring at an elevated temperature for one hour. Then water was added to the resultant mixture and 2-azido-4,4,5,5-tetrafluoro-5-bromopentanoate was extracted with ether, whereafter the ether was removed by drying. The residual liquid was vacuum distilled to afford 4.54 g (0.014 mol, yield of 60%) of ethyl 2-azido-4,4,5,5-tetrafluoro-5-bromopentanoate having b.p. 78° to 79° C./4 mm, nD20 1.4291, d420 1.564, νN3 2120 cm-1 and νC=O 1746 cm-1.
