Abstract
1,199,338. Berbine derivatives. ROUSSEL UCLAF. 19 Jan., 1968 [20 Jan., 1967], No. 3102/68. Heading C2C. The invention comprises novel N-(3-alkoxybenzylidene) (or 3-alkoxybenzyl) #-(3-alkoxyphenyl) ethylamines and acid addition salts thereof, which compounds are prepared by reaction of a #-(3-alkoxyphenyl) ethylamine with a 3-alkoxybenzaldehyde with subsequent reduction of the imine to give the amine with an alkali metal borohydride and a process for the production of compounds possessing a berbine ring system substituted by alkoxy groups in the 3- and 10-positions which comprises reacting an N-(3- alkoxy-benzyl) #-(3-alkoxyphenyl) ethylamine in the form of an acid addition salt thereof with glyoxal, which reaction is advantageously effected in the presence of a polar solvent, e.g. water or dioxan, and in the presence of a strong organic acid. Formic acid in the presence of water is particularly preferred. A mixture of 13-dehydroberbine and an acid addition salt of a 7,13-bis-dehydroberbine is obtained and at least one of said dehydroberbine derivatives is reduced, preferably by using an alkali metal borohydride, e.g. NaBH 4 , KBH 4 , hydrogen in the presence of a palladium catalyst, or zinc in the presence of acetic acid, to obtain the desired berbine derivative having alkoxy groups in the 3- and 10-positions.
