Lawesson's reagent → HCID 86594592, compound

Participants

Reaction Steps

Next, a Lawesson's reagent (2.2 g, 5.5 mmol) and chlorobenzene (20 ml) were added to 1,4-bis(4-hexadecyloxyphenyl)benzoylamino-2,5-dichloro-benzene 3 (4.0 g, 4.6 mmol) prepared above, and the mixture was heated under reflux for about 4 hr. After the completion of the reaction, the precipitated yellow powder was collected by filtration, was washed with ethanol, and was dried. Thereafter, the yellow powder thus obtained was recrystallized from DMF to give 1,4-bis(4-hexadecyloxyphenyl)thiobenzoylamino-2,5-dichloro-benzene 4 as the target compound (yield 90.2%).
