Reaction Steps

120 g (1 mole) of p-methylbenzaldehyde were heated to the boil on a water separator and under reflux with 181 g (1 mole) of phenylsulfonyl-acetonitrile in 500 ml benzene with addition of 6 ml of piperidine and 3 ml of glacial acetic acid. After 5 hours, 17 ml water had separated. Upon cooling to 10° C, the 1-p-tolyl-2-cyano-2-phenylsulfonyl-ethlene crystallized; after suction filtration, washing with 150 ml of cold benzene and drying, 206 g (73% of the theory) were obtained; melting point: 145°-147° C. ##STR14##
