Reaction Steps

To a solution of 2-chloro-6-(3-(4-fluorophenoxy) azetidin-1-yl)pyridine (500 mg, 1.79 mmoL) and 4-amino-N-methylbenzamide (270 mg, 1.79 mmol) in dimethylacetamide (5 mL, 3 mL/mmol) was added cesium carbonate (873 mg, 2.68 mmol) and the reaction was degassed for 15 min. Pd2(dba)3 (81 mg, 0.089 mmol) and BINAP (55 mg, 0.089 mmol) were added and the reaction was allowed to heat at 120° C. in the microwave. The reaction was quenched with water and extracted with EtOAc (2×50 mL). The organic extracts were washed with brine, dried over sodium sulfate, concentrated under reduced pressure and purified by silica gel column chromatography to afford 3-(6-(3-(4-fluorophenoxy) azetidin-1-yl)pyridin-2-ylamino)-N-methylbenzamide (61 mg, 13%) as a solid. Observed mass (M+1): 393.1. The following compounds were prepared as described in Example V above using appropriate starting materials.
