Yield:86-99-7 98.5%
Reaction Conditions:
in paraffin oil at 230; for 0.833333 h;Temperature;Solvent;
Steps:
1-3 Synthesis of hydroxy-7-chloroquinoline (8) (decarboxylation)
Add 120mL of paraffin oil to the reaction vessel and add it in batches when the temperature reaches 23040g of 7-chloro-4-hydroxyquinoline-2-carboxylic acid, continue to react for 50 minutes at this temperature after the addition is complete,It was filtered when the temperature dropped to 30°C, and the filter cake was washed and dried with petroleum ether to obtain 31.6 g of product, with a yield of 98.5%. Melting point 276-279°C.
