Procedure

A benzene solution containing benzophenone and 2,3-dimethyl-but-2-ene was placed in a photochemical reaction apparatus made of Pyrex (registered trade mark) into which argon gas was sealed, and while stirring, was exposed to ultraviolet radiation for 12 hours, employing a high pressure mercury lamp. Subsequently, after removing the solvent, vacuum distillation was performed, whereby a targeted compound was obtained.
