Procedure
20 Parts of 2-amino-5,6-dibenzyloxy-3,4-dihydro-1(2H)-naphthalenone hydrochloride is subjected to a procedure similar to that described in Reference Example 11 and the resultant 5,6-dibenzyloxy-2-trifluoroacetamido-3,4-dihydro-1(2H)-naphthalenone is reacted with 60 parts of 3-phenylpropanol p-toluenesulfonic acid ester under the same conditions as set forth in Reference Example 11. The reaction product is then hydrolyzed in a 47% aqueous solution of hydrogen bromide to obtain 3 parts of 5,6-dihydroxy-2-(3-phenylpropylamino)-3,4-dihydro-1(2H)-naphthalenone hydrobromide melting at 215°-217° C (decomposition).
