| 提纯方法 | The (±)-racemate is purified by distillation in a vacuum (b 90℃/1mm, 119-121℃/7mm, d 1.46) and it solidifies on cooling (m 36-37℃) [Overberger et al. Org Synth Coll Vol III 200 1955]. The (±)-tosyl derivative [114200-15-6] has m 56-57℃. The R-(+)-enantiomer is also purified by distillation in a vacuum (b110℃/3mm, d425 1.322, nD20 1.569) and has [α]D20 +39o(c1, CHCl3), +32.9℃(c1.39, MeOH). The S-(-)-enantiomer is similarly purified.
