标 题 :Synthesis of 3,5-diphenyl-4(1h)-pyridazinones
发明人：ABDULLA RIAZ F
权利人:LILLY CO ELI
摘要:A series of 3,5-diphenyl-4(1H)-pyridazinones are synthesized by a two-step process, both steps of which are new. In the first step, a phenylglyoxyloyl halide is reacted with a styrylamine in the presence of a base to form a 1-amino-2,4-diphenyl-1-buten-3,4-dione. In the second step, the enaminoketone formed in the first step is reacted with hydrazine or an alkylhydrazine to form the pyridazinone. Both steps of the reaction proceed in good yields at temperatures in the range of from about 0° C. to about 40° C. in the common reaction solvents.
