Reaction Steps
As in example 13 but starting from 3.16 g of 4-chloro-3-formyl-8-methoxy-thioflav-3-ene, 250 ml tert-butanol and 60 ml 2-methyl-2-butene. After work up the crude oil is crystallised in a mixture of n-hexane and ethyl acetate. Pure 3-carboxy-4-chloro-8-methoxy-thioflav-3-ene is obtained as yellow crystals; m.p. 207°-210° C.-TLC (SiO2, CH2Cl2 /Acetone/HCOOH 18/1/1): Rf =0.45.
