Reaction Steps

A 10 mL round bottomed flask equipped with stirbar and nitrogen inlet was charged with 1-[5-(aminomethyl)-2-fluorophenyl]-3-chloro-4-[(2,4-difluorobenzyl)oxy]-6-methylpyridin-2(1H)-one hydrochloride (250 mg, 0.56 mmol), dimethylcarbamyl chloride (52 μL, 0.56 mmol), triethylamine (195 μL, 1.4 mmol) and tetrahydrofuran (4.0 mL). After stirring at 25° C. for 5 min the reaction was completed by LC-MS. The reaction mixture was poured into a saturated aqueous NH4Cl solution. The aqueous mixture was extracted with ethyl acetate. The organic phase was dried with Na2SO4 and concentrated in vacuo to obtain the desired product (245 mg, 86%) as a white solid. 1H NMR (400 MHz, (CD3OD) δ 7.61 (q, J=7.9 and 6.7 Hz, 1H), 7.4 (m, 1H), 7.3 (d, J=9.3 Hz, 1H), 7.21 (m, 1H), 7.1 (m, 2H), 6.65 (s, 1H), 5.35 (s, 2H), 4.38 (s, 2H), 2.9 (s, 6H), 2.1 (s, 3H) ppm.
