実験手順

To a solution of [3,5-dichloro-4-(4-chloro-7-fluorothiazolo[5,4-c]pyridin-2-yl)phenyl]-carbamic acid tert-butyl ester (150 mg, 0.33 mmol) in dioxane (5 mL), was added (6-aminopyrimidin-4-yl)methanol (45 mg, 0.36 mmol), XantPhos (19.4 mg, 0.033 mmol) and Cs2CO3 (218.3 mg, 0.67 mmol). The resultant mixture was degassed with argon for 10 minutes before Pd2(dba)3 (57.7 mg, 0.063 mmol) was added and the reaction mixture was heated at 100° C. for 18 hours in a sealed vial. After cooling to room temperature, the reaction mixture was filtered through Celite® washing with EtOAc (5 mL). The resultant residue was purified by column chromatography on silica gel eluting with 0-80% EtOAc in cyclohexane to afford the title compound as a white foam (102 mg, 58%). LCMS (Method D): RT=3.35 min, m/z: 538 [M+H+].
