A mixture of aniline (1.0 g) and 2-ethoxy-1,1-bis(phenylsulphonyl)ethene (3.5 g) was heated at 160°-180° C. for 30 minutes, allowing any ethanol evolved to escape. After cooling, the residue was recrystallised by dissolving in a minimum of hot choroform and diluting with between 3 and 4 volumes of ethanol to give 1-phenylamino-2,2-bis(phenylsulphonyl)ethene (3.2 g), m.p. 199°-202° C.
