Yield:80-59-1 76.5%
Reaction Conditions:
with sulfuric acid at 140;
Steps:
1.2 2)Synthesis of tiglic acid IV
Th e37 g of concentrated sulfuric acid was taken and water 18.5 g was slowly added to prepare 67percentpercent sulfuric acid solution. To this was added 18.5 dag intermediate III and the external temperature was heated to 140 °C reflux. After cooling to an ice bath, 30percent g of crude product was added dropwise 100 dag, adjusted pH to 3-4, ethyl acetate was extracted three times (3×70mL), concentrated to 15 g of crude product, filtered with suction filtration to give white crystals m/m 1/3, yield 40 product m.p. 12 dag. GC chromatogram of the finished product. 76.5percent. 1 . 6.9 min degree. C. DMF solvent was filtered and the solvent content was taken up to 99percent above 63 - 64 °C.
