This invention relates to aseries of tripeptides of the general formula: ##STR1## wherein R = -- H, COCH.sub.3, alkylR.sub.1 = --oh, --nh.sub.2, --nh alkyl (C.sub.1 -C.sub.5) --O alkyl (C.sub.1 -C.sub.5)resulting from condensing of racemic, levorotatory and dextrorotatory phenylalanine and histidine and having an anti-ulcer activity.
摘要:
A process for preparing 1-(3,5-dimethoxy-4-hydroxy phenyl)-2-(N-methylamino) ethanol hydrochloride is described by reacting 2,6-dimethoxyphenol with anhydrous chloral in the presence of a catalyst, hydrolyzing 1-(3,5-dimethoxy-4-hydroxyphenyl)2,2,2-trichloro ethanol and subsequently isolating the 3,5-dimethoxy-4-hydroxyphenyl glyoxal thus obtained; finally, this compound, in the form of the bisulfite, is directly converted to the desired product by amination with methylamine in the presence of hydrogen with a hydrogenation catalyst and the final product is converted into the hydrochloride.
