الإجراء التجريبي

A 25 mL reseable vial was charged with bis(tri-tert-butylphosphine) palladium (0) (83 mg, 0.163 mmol) and N-(4-(3-bromopyridin-2-yloxy)phenyl)benzo[d]thiazol-2-amine (650 mg, 1.632 mmol). The vial was sealed and placed under an atmosphere of nitrogen. After addition of dioxane (5.38 ml), N-cyclohexyl-N-methylcyclohexanamine (1.072 ml, 4.90 mmol) and 3,4-dihydro-2H-pyran (549 mg, 6.53 mmol) were added and the mixture was heated to 105° C. Following complete consumption of the starting material, the reaction mixture was cooled to room temperature and transferred to a 100 mL round bottom flask, and the solvent was removed under reduced pressure. Following purification by silica gel chromatography the desired product was obtained as a racemic mixture. MS (ESI, pos. ion) m/z: 402.0 (M+1).
