Изобретение относитс к способу получени новых соединений, которые могут найти применение в фармацевтической промышленности . This invention relates to a process for the preparation of new compounds that can be used in the pharmaceutical industry.
Известен способ получени сложных эфиров карбоповых кислот путем взаимодействи карбоновой кислоты с безводным спиртом в присутствии сильной минеральной кислоты. Эта реакци обычно протекает при повышенной температуре и избытке одного из реагирующих веществ. При нагревании с другими спиртами происходит переэтерификаци .A known method for producing esters of carbopic acids by reacting a carboxylic acid with anhydrous alcohol in the presence of a strong mineral acid. This reaction usually proceeds at an elevated temperature and an excess of one of the reactants. When heated with other alcohols, transesterification occurs.
Предлагаетс основанный на известной реакции способ получени сложных эфиров 15 аденозин-5-карбоновой кислоты общей формулыA method for the preparation of 15 adenosine-5-carboxylic acid esters of the general formula
где R - алифатический или аралифатический остаток;where R is an aliphatic or araliphatic residue;
Z- два атома водорода или двухвалентный остаток ннзшего алкила,Z is two hydrogen atoms or a divalent residue of the lower alkyl,
заключающийс в том, что соответствующую аденозин-5-карбоновую кислоту обиден формулыthe fact that the corresponding adenosine-5-carboxylic acid is offended by the formula
