PROCEDURE
实验过程
A mixture of 6-bromo-4-chloro-2H-phthalazin-1-one and 7-bromo-4-chloro-2H-phthalazin-1-one (300 mg, 1.16 mmol), 4-(2-aminomethyl-4-methoxy-phenyl)-piperazine-1-carboxylic acid tert-butyl ester (338 mg, 1.05 mmol), Pd2(dba)3 (110 mg, 0.12 mmol), BINAP (217 mg, 0.35 mmol) and NaOt-Bu (327 mg, 3.48 mmol) in DMA (10 mL) was purged with nitrogen for 10 min. The mixture was heated at 90° C. for 1.5 h. The mixture was allowed to cool and diluted with ethyl acetate (30 mL) and washed with ammonium chloride (25 mL). The organic layer was dried and concentrated. Chromatography on silica yielded the title compound (102 mg, 18%) m/z (M+H)=500.32.
