Reaction Steps

A mixture of tert-butyl 4-(5′-chloro-6-fluoro-2,4′-bipyridin-2′-yl-amino)piperidine-1-carboxylate (200 mg, 0.492 mmol), DMSO (2 ml), TEA (0.137 ml, 0.983 mmol) and (3-fluorophenyl)methanamine (554 mg, 4.42 mmol) reaction mixture was flushed with argon and stirred at 100° C. for 40 hr, as the reaction mixture progress was followed by LCMS. The reaction mixture was cooled to room temperature, mixed with 150 ml of ethyl acetate, washed with saturated sodium bicarbonate (2×), water (3), saturated salt solution (1×), dried over sodium sulfate, filtered and concentrated to yield a crude material, which was purified by silica gel chromatography using a 12 g column, eluting from 0%-35% ethyl acetate with hexane. The desired fractions were collected and concentrated to constant mass, giving 225 mg of the title compound as a free base. LCMS (m/z): 512.3 (MH+), retention time=0.91 min.
