Good synthesis; product easy to isolate


Synthesized 2,6-Bis(3-dodecylthiophen-2-yl)benzobisthiazole following the procedure.

(1) The reaction was reproduced with higher yields (>25%).

(2) Added the 2-carboxylaldehydethiophene derviative by portions, used longer reaction time (24hs) and removed the acid gas during the reaction. The reaction yield was increased.

(3)   Although the yield was low and there are many side products, the spot of the product (yellow color) in the column is very easy to recognize.
