Reaction Steps

To a suspension of 4-{[2-(aminomethyl)-4-fluorobenzyl]oxy}-3-bromo-1-(2,6-difluorophenyl)-6-methylpyridin-2(1H)-one trifluoroacetate (0.13 g, 0.00023 mol) in THF (3.0 mL), was added triethyl amine (0.07 mL, 0.0005 mol) followed by the addition of trimethylsilylisocyanate (0.066 mL). The reaction mixture was stirred at room temperature for 1 h, and the desired product was isolated by reverse-phase HPLC purification using 10-90% CH3CN/Water (30 min gradient) at a flow rate of 100 mL/min. The appropriate fractions (m/z=496 M+H) were combined and freeze-dried, and the residue was partitioned between 5% sod. bicarbonate (20 mL) and dichloromethane (20 mL). The organic phase was washed with water, dried (Na2SO4) and concentrated to dryness under reduced pressure, to afford the title compound as a white amorphous powder (0.065 g): 1H NMR (DMSO-d6/400 MHz) δ 7.62 (m, 1H), 7.52 (m, 1H), 7.35 (m, 2H), 7.09 (m, 2H), 6.77 (s, 1H), 6.51 (t, 1H), 5.61 (s, 2H), 5.38 (s. 2H), 4.28 (d, 2H, J=6.0 Hz), and 2.02 (s, 3H); 19F NMR (DMSO-d6/400 MHz) δ−114.044 (m), and −120.31 (m); ES-HRMS m/z 496.0460 (M+H C21H18N3O3F3Br requires 496.0478).
