实验过程

A solution of 7-(3-chloro-propoxy)-4-(2-pyridin-2-yl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-3-yl)-quinoline (54 mg, 0.13 mmol), sodium iodide (5 mg, 0.03 mmol), and 2 N dimethylamine in tetrahydrofuran (3 mL, 6 mmol) in N,N-dimethylformamide (5 mL) is heated at 100° C. for 48 h. The mixture is cooled and concentrated in vacuo. The residue is chromatographed on SiO2 (100% ethyl acetate to 10% methanol in ethyl acetate) to yield the title compound, 41 mg (74%), as a brown solid.
