実験手順

To a solution of (Z)-1-cyclopropyl-4-(dimethylamino)-3-(2-(pyridin-4-ylamino)pyrimidin-4-yl)but-3-en-2-one (9) (200 mg, 0.618 mmol) in DMF (5.154 ml) was added potassium carbonate (256 mg, 1.855 mmol) and 2-methyl-2-thiopseudourea sulfate (129 mg, 0.928 mmol). The reaction was warmed to 120° C. and stirred for 1 hr. The solvent was evaporated and the crude residue partitioned between DCM and water. The organic layer was washed with brine, dried with sodium sulfate, and concentrated. The crude product was purified by flash chromatography with a gradient of 2-10% MeOH in DCM and further purified reverse phase HPLC with a gradient of 10-100% MeCN in H2O to give 7.8 mg of the desired product as a white solid. HRMS (ES+)=351.1391. UV-LC: 100/100% UV purity at 214/254 nm; HPLC: tR=3.38 minute over 7.75 minutes. 1H NMR (400 MHz, MeOD) δ ppm 0.10-0.14 (m, 2 H) 0.41-0.47 (m, 2 H) 1.03-1.15 (m, 1 H) 2.63 (s, 3 H) 2.94 (d, J=7.07 Hz, 2 H) 7.18 (d, J=5.56 Hz, 1 H) 7.83 (d, J=7.07 Hz, 2 H) 8.31 (d, J=7.07 Hz, 2 H) 8.64 (s, 1 H) 8.65 (d, J=5.05 Hz, 1 H)
