Reaction Conditions:

with palladium on activated charcoal;ammonium formate in water;butan-1-ol at 120; for 3 h;Further stages;Temperature;Solvent;Reagent/catalyst;

Steps:

2 Example 2
Mixing 32 g of 1,5-dihydroxynaphthalene, 8 g of water, 152 g of n-butanol, 3.2 g of palladium on carbon and 12.6 g of ammonium formate,The reaction was heated to 120 ° C under normal pressure for 3 h, and 12 g of sodium hydroxide was added to the obtained system.Stir and heat filtration, and adjust the pH of the obtained filtrate to 3 with industrial hydrochloric acid having a mass concentration of 31%.After the solid was precipitated, it was suction filtered, and the obtained cake was recrystallized from methanol and water (volume ratio of methanol to water: 4:1).Drying in vacuo gave 27.0 g of 5-hydroxy-1-tetralone.The liquid phase purity is greater than 99% and the yield is 83.3%.
