実験手順

To a DCM (0.1 mL) solution of (R)-6-(2-(2,5-difluorophenyl)pyrrolidin-1-yl)imidazo[1,2-b]pyridazin-3-amine (Preparation B; 6 mg, 0.019 mmol) cooled in an ice bath was added the isocyanatobenzene (2.5 mg, 0.021 mmol) in DCM (0.1 mL) dropwise. The reaction was slowly warmed to ambient temperature and stirred for 1 hour. The reaction was diluted with DCM (2 mL), washed with water, and concentrated. The crude product was purified by silica gel chromatography (eluent=50% EtOAc/hexanes first, then 5% MeOH in DCM) to yield the pure final product as a solid (5 mg, 60%). MS (apci) m/z=435.2 (M+H).
