Reaction Steps

In a three-necked flask equipped with a magnetic agitator, there are stirred 250 mg of 10-(2-thienyl)-1,8-dihydroxy anthrone, obtained according to example 8, in 5 cm3 of acetic anhydride and several drops of pyridine. The mixture is stirred for 3 hours at 80° C. under an inert atmosphere, then cooled. The expected triester crystallizes and is then filtered and washed with hexane, yielding 300 mg of light yellow crystals having a melting point of 260° C.
