Procedure

To a disposable sealed tube was charged 2-bromo-6-(3-(4-fluorophenoxy)azetidin-1-yl)pyridine (100.0 mg, 0.309 mmol), 3-amino-N-methylbenzamide (69.7 mg, 0.464 mmol), potassium carbonate (59.9 mg, 0.433 mmol) followed by X-Phos (2.95 mg, 6.19 μmol) and Pd2(dba)3 (1.417 mg, 1.547 μmol). The tube was fitted with a septum with an argon inlet for 5-10 min, when t-BuOH (1.0 mL) was added. The reaction mixture was then heated to 100° C. for 7 h, cooled to RT, diluted with EtOAc, and filtered through Celite® (diatomaceous earth) with EtOAc. The filtrate was concentrated and purified using MPLC (5 g cartridge, 12 g column, 0 to 75% EtOAc-hexanes) giving 3-(6-(3-(4-fluorophenoxy)azetidin-1-yl)pyridin-2-ylamino)-N-methylbenzamide (112.8 mg).
