Appropriate 6-(pyridin-2-yl)-5,6,7,8-tetrahydro-N-(1,2,3,4-tetrahydro-4,4-dimethyl-1-substituted)quinolin-7-yl)pyrido[4,3-d]pyrimidin-4-amine derivatives are prepared starting from 1,2,3,4-tetrahydro-4,4-dimethyl-7-nitroquinoline. The nitroquinoline derivate is reacted with appropriate alkylating agent to give the N-substituted nitroquinoline, which is reduced using standard procedures known in the art to yield 7-aminoquinoline derivative. The resulting aminoquinoline derivated is then condensed with the appropriate 4-chloro-6-(pyridin-2-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine to give the desired 6-(pyridin-2-yl)-5,6,7,8-tetrahydro-N-(1,2,3,4-tetrahydro-4,4-dimethyl-1-substituted)quinolin-7-yl)pyrido[4,3-d]pyrimidin-4-amine derivative. As a representative example, preparation of the N-morpholionethyl derivative is depicted in Scheme 6.
