Yield:-
Reaction Conditions:
with pyridine;thionyl chloride
Steps:
2; 5 Preparation of 2,6-bis(3,4-dimethoxystyryl)benzo[1,2-4,5]bisoxazole
Ferulic acid 5.2 gWas methylated with 17.8 g of dimethyl sulfate4.3 g of 3,4-dimethoxycinnamic acid was prepared,This was converted to pyridine,And acid chloride with thionyl chloride to give 3,4-dimethoxycinnamic acid chloride.To this was added 1.7 g of 2,6-dichloro-1,4-phenylenediamine and 100 ml of monochlorobenzene,And refluxed for 12 hours.After cooling down,The precipitate was filtered off,Washed to recover 1.8 g of a yellow solid.To 1.8 g of the above intermediate, 2.0 g of copper acetate,6 ml of pyridine and 20 ml of DMF were weighed, refluxed for 12 hours,After cooling down,The precipitate was filtered off,Column purification gave λ max 404 nm,To obtain the desired product having a melting point of 300 ° C. or higher.
