Procedure

6-{[3-bromo-4-[(2,4-difluorobenzyl)oxy]-6-methyl-2-oxopyridin-1(2H)-yl]methyl}nicotinic acid (from step 2) (230 mg, 0.5 mmol) was added into the 1-hydroxybenzotriazole (101 mg, 0.75 mmol) in 5 ml of N,N-dimethylforamide. 4-methyl morpholine (0.16 ml, 1.5 mmol) was added into the mixture followed by addition of 1-(3-(dimethylamino)propyl-3-ethylcarbodiimide hydrochloride (143 mg, 0.75 mmol). Stirred the mixture for 30 minute to become homogenous solution. To that homogenous solution, was added 2-(methylamino) ethanol (0.06 ml, 0.75 mmol) and the mixture was stirred for 20 hours. Water (150 ml) was added into the reaction mixture and the product was extracted using ethyl acetate (400 ml X2). The combined ethyl acetate solution was dried over anhydrous magnesium sulfate and evaporated to dryness. 1H NMR (400 MHz, DMSO-d6) δ 8.47 (app br s, 1H), 7.80 (br d, J=7.92 Hz, 1H), 7.64 (app q, J=6.58 Hz, 1H), 7.30 (m, 2H), 7.15 (m, 1H), 6.56 (s, 1H), 5.39 (s, 2H), 5.28 (s, 2H), 3.46 (m, 2H), 3.23 (m, 2H) 2.93 (m, 3H), 2.36 (s, 3H); LC/MS, tr=2.29 minutes (5 to 95% acetonitrile/water over 5 minutes at 1 ml/min with detection 254 nm, at 50° C.). ES-HRMS m/z 522.0850 (M+H calcd for C23H23BrF2N3O4 requires 522.0835).
