Purification Methods

Dissolve it in Et2O, wash it with H2O, dry it over K2CO3, filter, evaporate and dry the residue at 15mm, then recrystallise it from pet ether (b 40-60o), dry it at 25o/0.005mm and sublime it (sublimes slowly at room temperature)[Wittig & Pohmer Chem Ber 89 1334 1956, Gilman & Gorsich J Am Chem Soc 79 2625 1957].
