实验过程

Nitrogen is bubbled through a solution of 7-bromo-4-[2-(6-methyl-pyridin-2-yl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-3-yl]-quinoline (0.050 g, 0.12 mmol), tributylamine (0.032 mL, 0.17 mmol), methyl acrylate (0.027 mL, 0.24 mmol), and N,N-dimethylformamide (0.5 mL) in toluene (1.0 mL) for 20 min. Pd(OAc)2 (0.002 g, 0.006 mmol) and tri(o-tolyl)phosphine (0.007 g, 0.021 mmol) are added and nitrogen bubbled through the reaction mixture for 10 min. The mixture is heated to 80° C. for 24 h. An additional portion of Pd(OAc)2 (0.002 g, 0.006 mmol) and tri(o-tolyl)phosphine (0.007 g, 0.021 mmol) is added and heating continues for another 24 h. The reaction is cooled and concentrated in vacuo and the residue chromatographed on SiO2 (2% methanol in methylene choloride) to yield the title compound, 0.49 g (97%), as a yellowish solid.
