실험 절차

A mixture of N-(4-(3-iodopyridin-2-yloxy)phenyl)benzo[d]thiazol-2-amine (0.403 g, 0.905 mmol), N-methyldicyclohexylamine (0.400 mL, 1.886 mmol, Aldrich), bis(tri-tert-butylphosphine)palladium (0) (0.045 g, 0.088 mmol, Strem) and 2,5-dihydrofuran (0.500 mL, 6.78 mmol, Aldrich) in 5 mL of dioxane was capped under an atmosphere of argon and stirred at rt for 3 h and then heated at 45° C. overnight. The reaction mixture was diluted with MeOH, evaporated onto silica gel and purified by flash chromatography (Isco, (40 gram)) eluting with 2M NH3 in MeOH:CH2Cl2 (0:1→3:97) to give a white amorphous solid. MS (ESI, pos. ion) m/z: 386.0 (M+1).
