摘 要:阐述了一种PARP抑制剂氟唑帕利{4-[[4-氟-3-[3-(三氟甲基)-6,8-二氢-5 H-(1,2,4)三唑并(4,3-a)吡嗪-7-羰基]-苯基]甲基]-2 H-酞嗪-1-酮(1)}的合成方法。该方法以2-(三氟甲基)-(1,2,4)三唑并(1,5-α)吡嗪(2)为原料,经过氢化反应得到5,6,7,8-四氢-2-(三氟甲基)-(1,2,4)三唑并(1,5-α)吡嗪(3),化合物3与5-[(3,4-二氢-4-氧代-1-酞嗪基)甲基]-2-氟-苯甲酸(4)缩合得到化合物(1)。该工艺路线简短,操作简便,副反应少,反应收率高,适合工业化生产。Synthesis process of a PARP inhibitor of Fuzuopali {4-[-[3-[-[3-(trifluoromethyl)-5,6,7,8-dihydro- 5 H- (1,2, 4 ) triazoloc ( 4, 3-α ) pyrazine-7-yl ] carbonyl ]-4-fluorophenyl ] methyl } ( 2 H ) phthalazine-1-one, 1 ) was described in this paper. This synthesis process using 2-(trifluoromethyl)-(1,2,4) triazolo(1,5-α) prrazine(2) as the starting material which is hydrogenated to give 5,6,7,8-4-hydro-2-(trifluoromethyl)-(1,2,4)triazolo(1,5-α) prrazine (3). The Compound 1 was obtained by reacting compound 3 with 2-fluoro-5-(4-oxo-3,4-dihydrophthalazineyl) methyl) benzoic acid. The synthetic process is suitable for industrial production with short synthetic route, simple operation and high reaction yield.
