実験手順

4-(4-(2-(Methylthio)-6-oxo-1,6-dihydropyrimidin-5-yl)pyrimidin-2-ylamino)benzonitrile (34) (700 mg, 2.081 mmol) was dissolved in POCl3 (1940 μl, 20.81 mmol), then the reaction mixture was heated at 120° C. for 3 hours. The reaction mixture was cooled to rt, then was slowly poured into an ice-cooled saturated Na2CO3 solution while stirring vigorously. The reaction mixture was then adjusted to pH 7 with additional Na2CO3 solution. DCM was added to the mixture and the aqueous layer was extracted twice with DCM. The organic extracts were combined, washed with brine, dried over sodium sulfate, then concentrated in vacuo to obtain the desired product as a bright yellow solid (428 mg, 53% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 2.62 (s, 3H) 7.39 (d, J=5.05 Hz, 1H) 7.74 (m, 2H) 8.00 (m, J=9.09 Hz, 2H) 8.69-8.80 (m, 1H) 8.93 (s, 1H) 10.42 (s, 1H). MS (ES+): m/z=355.3 (100) [MH+]. HPLC: tR=1.57 minutes over 3 minutes. Purity: 91% [HPLC (LC/MS) at 220 nm].
