| Abstract: | A method has been developed for the synthesis of 4-amino-substituted 7-benzyl-2-morpholin-4-yl-5,6,7,8-tetrahydropyrido3,4-d]pyrimidines
by condensation of ethyl 1-benzyl-3-oxopiperidine-4-carboxylate with morpholine-4-carboxamidine and subsequent reaction of
the 7-benzyl-2-morpholin-4-yl-5,6,7,8-tetrahydro-3H-pyrido3,4-d]pyrimidin-4-one with trifluoromethanesulfonic anhydride and
secondary amines.
