実験手順
Stir a solution of 2-[4-(2-pyridin-2-yl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-3-yl)-quinolin-7-yloxy]-ethanol (293 mg, 0.78 mmol) and methane sulfonyl chloride (68 μL, 0.81 ml) in dried pyridine (5 mL) for 2 hours. Remove the pyridine in vacuo and recover the residue with chloroform. Wash the organic layer with saturated sodium bicarbonate and dry over sodium sulfate to give the desired subtitled intermediate as a white foam (425 mg, 100%). MS ES+ m/e 451.1 (M+1).
