Abstract: front page image
(EN)[PROBLEMS] A process for obtaining 6,7-bis(2-methoxyethoxy)­quinazolin-4-one in a high yield from ethyl 2-amino-4,5­bis(2-methoxyethoxy)benzoate. [MEANS FOR SOLVING PROBLEMS] The process for producing 6,7-bis(2-methoxyethoxy)quinazolin-4-one comprises reacting ethyl 2-amino-4,5-bis(2-methoxyethoxy)benzoate with a formic acid compound in the presence of an ammonium carboxylate.
(FR)L'invention concerne un procédé de production de 6,7-bis(2-méthoxyéthoxy)-quinazolin-4-one avec un rendement élevé à partir de 2-amino-4,5-bis(2-méthoxyéthoxy)benzoate. Ce procédé de production de 6,7-bis(2-méthoxyéthoxy)-quinazolin-4-one consiste à faire réagir du 2-amino-4,5-bis(2-méthoxyéthoxy)benzoate avec un composé d'acide formique en présence d'un carboxylate d'ammonium.
(JA)【課題】 2−アミノ−4,5−ビス(2−メトキシエトキシ)安息香酸エチルから高い収率で6,7−ビス(2−メトキシエトキシ)キナゾリン−4−オンを得る方法を提供する。 【解決手段】 2−アミノ−4,5−ビス(2−メトキシエトキシ)安息香酸エチルとギ酸化合物とをカルボン酸アンモニウムの存在下にて反応させることからなる6,7−ビス(2−メトキシエトキシ)キナゾリン−4−オンの製造法。
