Purification Methods

This yellow solid is purified by passage through a silica gel column, eluting with *C6H6/Me6CO, evaporating and crystallising the residue from EtOH. The sulfoxide [65373-82-2] has m 133-135o, and the sulfone [22810-82-2] has m 136.5-137o (from EtOH). The dimethylhydrazone has m 111-113o (from BuOH). It forms easily hydrolysable salts.
