Participants

Reaction Steps

To a solution of (S)-3-bromo-N-(pyrrolidin-2-ylmethyl)imidazo[1,2-b]pyridazin-6-amine (400 mg, 1.2 mmol) and triethylamine (0.5 mL, 3.5 mmol) in DCM (10 mL) was added t-butyl isocyanate (0.2 mL, 1.75 mmol) dropwise. After stirring at it for 2 h, the reaction mixture was concentrated and purified by ISCO column chromatography (10% MeOH/DCM) to give (S)-2-(((3-bromoimidazo[1,2-b]pyridazin-6-yl)amino)methyl)-N-(tert-butyl)pyrrolidine-1-carboxamide (360 mg, 76% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.58 (d, J=9.60 Hz, 1H), 7.42 (s, 1H), 6.72 (d, J=9.85 Hz, 1H), 5.07 (s, 1H), 4.26 (dd, J=6.57, 1.77 Hz, 1H), 3.35-3.48 (m, 4H), 2.09-2.20 (m, 1H), 1.90-2.05 (m, 3H), 1.26 (s, 9H); LRMS (ESI) m/e 395.2 [(M+H)+, calcd for C16H24BrN6O 396.3].
