Reaction Conditions:

with hydrogen in methanol at 150; under 16501.7 Torr; for 4 h;Autoclave;Solvent;Temperature;Pressure;

Steps:

1-11

In an autoclave with a volume of 250 mL,Add 150 mL of methanol, 6 g of 1,8-diaminonaphthalene and 0.6 g of Raney nickel.Closed system,After replacing the air in the kettle with hydrogen,At 2.0Mpa hydrogen pressure,The reaction was carried out at 150 ° C for 5 hours.Cooling the discharge,After filtering the reaction mixture, the solvent was evaporated under reduced pressure to give 5,6,7,8-tetrahydro-1-naphthylamine.Yield 98.2%,The purity was 98.1% (GC).
