with a split ratio of 10 and the following temperature ramp 60 u00b0 c far 5 min ramping up at 10 u00b0 c min to 320 u00b0 c and held for 5 min the detector temperature was set at 280 u00b0 c dthfp gc profile shows two separated peaks with different close retention times corresponding to the two diastereoisomers mesa diastereoisomer correspond to the peak with the lowest retention time the sample being validated by the analysis methods in the previous paragraph the experimental work showing in tables 1 and 2 was performed using a biotage endeavor u00ae an automated catalyst screening system with reactors setup in parallel each reactor has a working volume up to 7 ml is equipped with an internal glass tube and a paddle stirrer and can withstand pressures of up to 50 bars 2 2 di 2 furyl propane dfp 1 575 g 8 94 mmol with 31 5 mg of wet catalyst commercial 5 pd c 50 water at 2 wt to which was added commercial powdered inorganic salts 0 5 mole equivalent of the cation vs dfp with respect to the results in table 1 and 2 the contents were heated with with stirring set.
