Versuchsvorschrift

To a solution of 6-bromoimidazo[1,2-a]pyridin-2-amine (200 mg; 0.94 mmol) in dry THF (4 mL) was added NaH (90 mg; 3.76 mmol) in portions at 0° C. The reaction mixture was stirred at r.t. for half an hour. Then 2-chloro-4-(pyrrolidin-1-ylmethyl)pyridine (222 mg, 1.1 mmol) was added. The mixture was heated to 120° C. for 24 hrs. The mixture was quenched by addition of H2O (20 mL) slowly at 0° C., extracted with DCM (30 mL×3). The combined organic phases were concentrated under reduced pressure and purified by column chromatography on silica (DCM:MeOH=15:1) to obtain 6-bromo-N-(4-(pyrrolidin-1-ylmethyl)pyridin-2-yl)imidazo[1,2-a]pyridin-2-amine (110 mg, yield 80%) as a brown solid.
