Participants

Reaction Steps

8 g (24.4 mmole) 1,3,3a,4,7,7a-hexahydro-1,3-dioxo-5,6-bis(trimethylsiloxy)-isoindole and 11.4 g (80 mmole) 4-chlorophenyl hydrazine are boiled under reflux for 16 hours in 50 ml methanol and 50 ml glacial acetic acid. The crystals precipitated out after cooling are filtered off, after-washed several times with methanol, and dried. One obtains 5-[(4-chlorophenyl)-azo]-6-[N'-(4-chlorophenyl)-hydrazino]-1,3,3a,4,7,7a-hexahydro-1,3-dioxoisoindole in the form of yellow-green crystals.
