Procedure

A vial was charged with 8-((6-aminopyrimidin-4-yl)amino)-2-benzyl-10-methyl-2,3,4,5-tetrahydropyrido[1,2-a][1,4]diazepine-1,7-dione (9, 0.3 g, 76.9 mmol) and triflic acid (7.0 mL) was added. The reaction mixture was heated under microwave at 150° C. for 20 min. TLC showed completion of the reaction and the mixture was cooled to ambient temperature. This was then basified with aqueous sodium bicarbonate solution and extracted with 5% methanol/dichloromethane (3×200 mL). The organic layer was dried over sodium sulfate and solvent was removed under reduced pressure to afford 8-((6-aminopyrimidin-4-yl)amino)-10-methyl-2,3,4,5-tetrahydropyrido[1,2-a][1,4]diazepine-1,7-dione (Cpd. No. 217) as a brown solid. Yield: 0.06 g, 26%; MS (ESI) m/z 301.15 [M+1]+; 1H NMR (400 MHz, DMSO-d6) δ 8.51 (s, 1H), 8.36-8.20 (m, 2H), 8.15 (s, 1H), 6.52 (brs, 2H), 6.13 (s, 1H), 5.05 (brs, 1H), 3.26-3.04 (m, 2H), 2.95-2.80 (m, 1H), 2.13 (s, 3H), 1.87 (brs, 2H).
