Reaction Steps

A mixture of crude N-({(2R,5R)-4-[2-amino-6-(4-cyano-3-fluorophenyl)-4-pyrimidinyl]-5-methyl-2-morpholinyl}methyl)-2,2-dimethylpropanamide (0.29 mmol theoretical) and hydrazine monohydrate (0.28 mL, 5.78 mmol) in ethanol (3 mL) was stirred at 100° C. in a sealed tube for 17 hours. The mixture was concentrated in vacuo and the residue was purified on a Gilson reverse phase HPLC (CH3CN/water with 0.1% TFA). The product fractions were combined and concentrated in vacuo, taken up in EtOAc (15 mL), washed with saturated aqueous NaHCO3 (2×10 mL) and brine (10 mL), then dried (Na2SO4), filtered, and concentrated in vacuo to afford the title compound (81 mg) as a pale yellow solid. LC-MS (ES) m/z=439 [M+H]+. 1H NMR (400 MHz, DMSO-d6): δ 1.13 (s, 9H), 1.17 (d, J=6.6 Hz, 3H), 2.64-2.84 (m, 1H), 3.20-3.30 (m, 2H), 3.42-3.52 (m, 1H), 3.63 (dd, J=11.4, 2.5 Hz, 1H), 3.77 (d, J=11.1 Hz, 1H), 3.98-4.79 (bs, 2H), 5.39 (s, 2H), 6.12 (s, 2H), 6.50 (s, 1H), 7.53 (d, J=8.3 Hz, 1H), 7.63 (t, J=5.7 Hz, 1H), 7.71 (d, J=8.3 Hz, 1H), 7.93 (s, 1H), 11.53 (s, 1H).
