Tetrahedron Letters, 25, p. 3463, 1984 DOI: 10.1016/S0040-4039(01)91048-2
Purification Methods
Purify the ketone first through a 24inch column packed with Raschig rings, then a 40cm Vigreux column (p 11) under reduced pressure (b 69-69.3o/7mm, see above). The oxime has m 144-145o (from 60% EtOH), and the semicarbazone has m 196-197o, 197-198o (214.5o, 217-218o) [Karasch & Tawney J Am Chem Soc 63 2308 1941, UV: Sandris & Ourisson Bull Soc Chim Fr 958 1956].
