Reaction Steps

3-((Z)—((R)-2-amino-7-(4-fluoro-2-(6-methoxypyridin-2-yl)phenyl)-4-methyl-7,8-dihydropyrido[4,3-d]pyrimidin-5(6H)-ylidene)aminooxy)dihydrofuran-2(3H)one (14.3 mg, 0.03 mmol) was dissolved in 7N NH3-MeOH solution and stirred overnight in a sealed tube. The solvent was removed and residue dried to afford the title compound 2-((Z)—((R)-2-amino-7-(4-fluoro-2-(6-methoxypyridin-2-yl)phenyl)-4-methyl-7,8-dihydropyrido[4,3-d]pyrimidin-5(6H)-ylidene)aminooxy)-4-hydroxybutanamide (13.2 mg, 89%) as a white solid. 1H NMR (400 MHz, METHANOL-d4) δ 1.83-2.16 (m, 2H) 2.58 (d, J=6.06 Hz, 3H) 2.85-3.03 (m, 1H) 3.07-3.25 (m, 1H) 3.70 (q, J=7.24 Hz, 2H) 3.90 (d, J=11.37 Hz, 3H) 4.54 (td, J=7.83, 5.05 Hz, 1H) 4.97-5.17 (m, 1H) 6.69-6.85 (m, 1H) 7.11 (dd, J=7.71, 2.40 Hz, 1H) 7.14-7.26 (m, 2H) 7.57-7.72 (m, 1H) 7.76 (dd, J=15.03, 6.69 Hz, 1H). MS (ES) [M+H] calculated for C24H27FN7O4, 496.50. found 496.40.
