반응 단계

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 N,N-dimethylformamide under an atmosphere of nitrogen and then 17 g. of p-anisoyl chloride was added to produce 35 g. of 3-hydroxy-4-(p-anisoyloxy)phenyl test-butylaminomethyl ketone, m.p. 170°-175° C. (dec.)(uncorr.), which was converted to 28 g. of the hydrochloride, m.p. 235° C. (dec.)(uncorr.). This hydrochloride (26 g.) was catalytically hydrogenated, using a procedure similar to that described above in Example 30B, to yield 19 g. of 3-hydroxy-4-(p-anisoyloxy)-alpha-(tert-butylaminomethyl)-benzyl alcohol hydrochloride as a white crystalline solid which melted at 211°-213° C. (dec.)(uncorr.). By interacting this hydrochloride with p-anisoyl chloride and with acetyl chloride, there are obtained 3-hydroxy-4-(p-anisoyloxy)-alpha-(tert-butylaminomethyl)benzyl p-anisate hydrochloride and 3-hydroxy-4-(p-anisoyloxy)-alpha-(tert-butylaminomethyl)benzyl acetate hydrochloride, respectively.
