Procedure

To a solution of 5-((6-aminopyrimidin-4-yl)amino)-3-chloro-N,1-bis(4-methoxybenzyl)-6-oxo-1,6-dihydropyridine-2-carboxamide (6, 0.40 g, 0.77 mmol) in dichloromethane (10 mL) was added trifluoroacetic acid (20 mL) and trifluoromethanesulfonic acid (1 mL) at 0° C. The reaction mixture was stirred at 70° C. for 2 h. After completion, the reaction mixture was concentrated and basified by aq. ammonia at 0° C. The precipitate obtained was collected by filtration, washed with water and dried to obtain the crude. The crude was stirred with methanol, filtered, washed with pentane and dried to afford 5-((6-aminopyrimidin-4-yl)amino)-3-chloro-6-oxo-1,6-dihydropyridine-2-carboxamide (Cpd. No. 214) as yellow solid. Yield: 0.035 g, 16%; MS (ESI) m/z 281.05 [M+1]+; 1H NMR (400 MHz, DMSO-d6) δ 12.02 (s, 1H), 8.66 (s, 1H), 8.50 (s, 1H), 8.17 (s, 1H), 7.92 (s, 1H), 7.86 (s, 1H), 6.53 (s, 2H), 6.18 (s, 1H).
