Procedure
Using a procedure similar to that described above in Example 58A, 26 g. of 3,4-dihydroxyphenyl tert-butylaminomethyl ketone hydrochloride was reacted with 16 g. of sodium methoxide in 300 ml. of N,N-dimethylformamide under an atmosphere of nitrogen and then 17 g. of p-anisoyl chloride was added to produce 3-hydroxy-4-(p-anisoyloxy)phenyl tert-butylaminomethyl ketone hydrochloride. This salt was converted to the free base which was treated with acetic acid to yield 35 g. of the acetate salt, m.p. 170°-175° C. (dec.)(uncorr.). By treating the salt in N,N-dimethylformamide with concentrated hydrochloric acid there was obtained 28 g. of the hydrochloride salt, m.p >235° C. (dec.)(uncorr.). When this hydrochloride is catalytically hydrogenated, using a procedure similar to that described above in Example 30B, there is obtained 3-hydroxy-4-(p-anisoyloxy)-alpha-(tert-butylaminomethyl)benzyl alcohol hydrochloride.
