3-Diphenyl-5-formyl-6-methoxybenzofuran was reacted with hippuric acid to give 4-[(2′,3′-diphenyl-6′-methoxy-5′-benzofuranyl)methylene]-2-phenyloxazolin-5-one. The above mentioned oxazolone yielded 2,3-diphenyl-6-methoxybenzofuranylacetic acid by reaction with hydrazine hydrate, nitrous acid, benzene followed by acid hydrolysis. The reactions of the oxazolone with hydroxylamine hydrochloride and primary or secondary
使2,3-二苯基-5-甲酰基-6-甲氧基苯并呋喃与马尿酸反应,得到4-[((2',3'-二苯基-6'-甲氧基-5'-苯并呋喃基)亚甲基] -2-苯基恶唑啉-5 -一。通过与水合肼,亚硝酸,苯反应,然后酸水解,上述恶唑酮生成2,3-二苯基-6-甲氧基苯并呋喃内酯酸。还研究了恶唑酮与盐酸羟胺和伯胺或仲胺的反应。
