A method for producing compounds of the formula:
Wherein R2 is selected from the group consisting of amino, lower alkylamino, di-lower alkylamino, allylamino, diallylamino, N-lower alkyl-N-allylamino, benzylamino, dibenzylamino, phenethylamino, diphenethylamino, 4-hydroxyphenethylamino or di-(4-hydroxyphenethylamino);
comprising:
a) reacting
with Wittig Reagent to produce
wherein R1 is alkoxyl;
f) hydrolyzing compound II under acidic conditions to produce
g) subjecting compound III to reduction and amination to produce the tertiary amine
wherein R2 is as defined above;
h) reacting compound IV with
4-chlorophenoxyacetonitrile to create nucleophilic substitution to produce the nitrile compound
wherein R2 is as defined above; and
i) effecting reduction and hydrolysis in the same step with palladium/C and sodium hydroxide to produce
wherein R2 is as defined above.
一种用于制备以下化合物的方法:其中R2选自氨基、低烷基氨基、二烷基氨基、烯丙氨基、二烯丙氨基、N-烷基-N-烯丙氨基、苄氨基、二苄氨基、苯乙基氨基、二苯乙基氨基、4-羟基苯乙基氨基或二-(4-羟基苯乙基氨基)等基团的方法;包括:a)将与Wittig试剂反应以产生其中R1为烷氧基;f)在酸性条件下水解化合物II以产生g)将化合物III进行还原和胺化以产生三级胺,其中R2如上所定义;h)将化合物IV与4-氯苯氧乙腈反应,进行亲核取代以产生腈化合物,其中R2如上所定义;并i)在同一步骤中使用钯/C和氢氧化钠进行还原和水解以产生其中R2如上所定义。
