Participants

Reaction Steps

In a manner similar to that of Example 9, 4 parts of 2-amino-1,5,6-trihydroxy-1,2,3,4-tetrahydronaphthalene hydrobromide is reacted with 20 parts of 4-hydroxyphenylacetone. The reaction product is dissolved in ethanol and ethyl acetate is added to the solution. The procedure yields 2 parts of 2-(4-hydroxy-α-methylphenethylamino)-1,5,6-trihydroxy-1,2,3,4-tetrahydronaphthalene fumarate as colorless crystals melting at 137°-141° C.
