Procedure

30.2 g of 2,3-bis(4-methoxyphenyl)-3-chloro-acrylaldehyde (0.1 mol) were dissolved in 250 ml of pyridine and heated for half an hour on the steam bath together with 30 g of hydroxylamine hydrochloride. Then the solution was evaporated; the remaining solid substance was taken up with ethanol. The whole was boiled, suction-filtered and dried. The 2,3-bis(4-methoxyphenyl)-3-chloro-acrylaldoxime had a melting point of from 207° to 208° C (decomposition). The following compounds were prepared according to the same process:
