摘要：
FIELD: medicine, pharmaceutics.SUBSTANCE: invention refers to producing new 5,8,9,10-tetrahydropyrimido[4,5-d]azocine derivatives having triflate, secondary and tertiary amino groups in the 4th position of general formula specified below. In general structural formula: 2-12 2 X=OTf (Tf means triflate), X means NR1R22 related to the groups 3-12.The method consists in the fact that 6-isopropyl-2-phenyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4(3H)-one reacts with methyl propyolate in methanol at room temperature to produce methyl 8-isopropyl-4-oxo-2-phenyl-5,8,9,10-tetrahydropyrimido[4,5-d]azocine-6-carboxylate (1). Thereafter, the prepared compound reacts with triftalane hydride in dichloromethane in the presence of pyridine at t°=-10°C it is recovered and purified with by means of column chromatography to prepare methyl 8-isopropyl-2-phenyl-4-{[(trifluoromethyl)sulphonyl]oxy}-5,8,9,10-tetrahydropyrimido[4,5-d]azocine-6-carboxylate (2) then the solution I mmole of the prepared product (2) in absolute dioxide is added with 2 mmole of K2CO3 and 1.5 mmole of appropriate amine. After being boiled for two hours and removing the solvent, respective 4-amino substituted 5,8,9,10-tetrahydropyrimido[4,5-d]azocine of formula 3-12 is prepared. The method is directed to prepare the products in the form of white or yellow powder, or in the form of drying oil.EFFECT: after the primary screening, the compounds appeared to be acetyl- and butyrylcholin esterase inhibitors and can find application as scaffolds in searching the preparations for treating neurodegenerative diseases.10 exИзобретение относится к получению новых производных 5,8,9,10-тетрагидропиримидо[4,5-d]азоцинов, имеющих в 4-м положении трифлатную, вторичную и третичную аминогруппы общей формулы, указанной ниже. Соединения при первичном скрининге проявили себя в качестве ингибиторов ацетил- и бутирилхолинэстераз и могут найти применение в качестве скаффолдов при поиске препаратов для лечения нейродегенеративных заболев
