General procedure: Intermediates 8 (1 eq) and respective 9-chloroacridine derivatives 4a-4f (1.1 eq) were added to a round flask, and then excessphenol was added as solvent. The reaction system was warmed up to 60 C until phenol was melted and stirred for 0.5 h under argonprotection. Then the mixture was warmed up to 120 C and continued to reaction for more 2 h. After the reaction was completed, themixture was added to ethyl ether drop by drop [2]. The precipitate was filtered and washed twice with new ethyl ether to give pureproducts 9a-9f, which were then characterized by 1H NMR, 13C NMR, melting point and high resolution mass spectrum (HRMS, ESI).

To a solution of compound 1.3.2a dispersed in 200 mu of acetonitrile was added HBTU (500 mug, 131 mmol) and 1.4.2 (500 mug , 137 mmol). The reaction was kept at 32 C in a shaker for 3 hours at 700 rpm. The final product was isolated by HPLC employing a C18 Atlantis T3 column (4.6 x 250 mm, 5 muiotaeta) with the following eluents: water as solvent A and acetonitrile as solvent B, going from 5 % of B to 100% of B in 15 minutes and then 100% of B from 15.01 minutes to 25 minutes. The fractions containing the radioligand were dried in vacuum, obtaining a white solid as product.

We know that the rate of many reactions can be accelerated by catalysts. A catalyst speeds up the rate of a reaction by lowering the activation energy; in addition, the catalyst is regenerated in the process. 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one, cas is 763111-47-3,the phthalazine compound, below Introduce a new synthetic route., 763111-47-3
