Reaction Conditions:
with hydrogen in ethanol at 25 - 30;
Steps:
4 Example 4
250ml single-necked reaction flask was charged with 12 g (0.084 mol) of 2-aminonaphthalene and dissolved in 180 ml of ethanol. The resulting solutionLiquid were added 1.5g additives diatomaceous earth, particle size 19.6μm; 1.2g catalyst Ni, the resulting system atmospheric pressure into the hydrogen, and in the roomTemperature (25 -30 ) reaction was stirred. When the system is no longer hydrogen absorption, the reaction is complete, standing and filtering, the filter cake with 15ml of ethanolWashed twice, the filtrate was concentrated under reduced pressure at 60 ° C and evaporated to give 5,6,7,8-tetrahydro-2-amino naphthalene 11.7g, 95% yield, purity98.4% (HPLC).
