SU419034A3 (ru) | СПОСОБ ПОЛУЧЕНИЯ ПРОИЗВОДНЫХ ХИНАЗОЛИНА1Изобретение относитс к способу получени новых производных хиназолина, которые обладают улучшенными лекарственными свойствами и могут найти нрименение в фармацевтической промышленности.Предлагаетс основанный на известной реакции алкилировани хиназолннов способ получени производных хиназолина общей формулы ICnH,n--R.Примером галоида в формуле I могут служить атомы хлора, брома, фтора и йода; Ci—С4-алкилов — метил, этил, н-пропил, изо- пропил, н-бутил, изобутил и т/?ет-бутил; 5 Ci—С4-алкоксильных групп — метокси-, эток- СИ-, н-пропокси-, изопронокси-, н-бутокси-, изо- бутокси- и грег-бутоксигруппы; Сз—Се-цикло- алкилов — циклопропил, циклобутил, цикло- пентил, циклогексил, метилциклопропил, ди- 10 метилциклопронил и т. п. группы. Когда СпН2п группа — алкилен с 1—3 атомами углерода, она может быть представлена такими группами, как метиленова , этиленова , 1-метилэти- ленова , 2-метилэтиленова и триметиленова .где D — группаСпособ получени соединений формулы 1 заключаетс в том, что 1-незамеш,енное производное хиназолина общей формулы П15Нг; , :- ;-О "^ О ."^ -'.RI, R2 и Rs каждый — водород, галоид, нит- рогруппа, Ci—С4-алкил, Ci—Сгалкоксил, С\—С4-алкилтиогруП'Па, Ci—С^алкилсульфо- группа, Ci—С4-алкилсульфинильна группа, грифторметил;R4 — Сз—Сб-циклоалг-'ил;W — кислород или сера;п — О или целое число от 1 до 3.2025где RI, Ra, D и W имеют вышеуказанные зна- 30 чени . | |
