Yield: 78%

Reaction Conditions:

with copper(I) oxide;1D-1-O-Methyl-muco-inostol;sodium hydroxide in water at 130; for 6 h;

Steps:

19 Example 19: Preparation of 7-hydroxyquinoline:
In the l00mL hydrothermal synthesis reactor,Add sodium hydroxide (3 mmol), water (5 mL), stir and dissolve,Add 7-bromoquinoline (0.5 mmol), cuprous oxide (0.05 mmol),White hardwood alcohol (0.05 mmol), the reaction was stirred evenly at 130 ° C for 6 hours.After cooling, the pH was adjusted to 8 with dilute hydrochloric acid and extracted with ethyl acetate.The extract is concentrated and subjected to column chromatography to give 7-hydroxyquinoline, 57.3 mg.The yield was 78%.
