Dimethyl Sulfoxide → Tert-butyl 3-(5-(3-((7-methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)pyridin-2-ylamino)pyrrolidine-1-carboxylate

反応手順

A 0.5-2 mL microwave vial was charged with 4-((6-(6-fluoropyridin-3-yl)-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methoxy)-7-methoxyquinoline (0.100 g, 0.249 mmol), tert-butyl 3-aminopyrrolidine-1-carboxylate (0.116 g, 0.622 mmol), and DMSO (4.00 ml, 56.4 mmol), sealed and placed in a Personal Chemistry microwave for 1 hour at 100° C. and then 30 minutes at 120° C. Water was added slowly to the reaction mixture until a precipitate formed. The solid was collected and purified by MPLC using a 40 g RediSep column, eluting with a gradient of 3-6% MeOH/DCM over 40 minutes. The solid was triturated with MeCN and filtered; the mother liquor was concentrated to give tert-butyl 3-(5-(3-((7-methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)pyridin-2-ylamino)pyrrolidine-1-carboxylate.
