Reaction Steps

In an 4-mL was charged with 2-[4-[[2-(5-Chloro-2-thienyl)-5-ethyl-6-methyl-pyrimidin-4-yl]amino]phenyl]acetonitrile (16 mg, 0.043 mmol), azidotrimethylsilane (80 mg, 1.44 mmol) and tetrabutylammonium fluoride trihydrate (20 mg, 0.057 mmol). The mixture was stirred at 110° C. overnight. After cooling to room temperature, the mixture was dissolved in dichloromethane (2 ml) and 2N HCl (aq.) (1 ml) was added. The precipitate was collected by filtration and washed with water (5 ml) followed dichloromethane (5 ml). After dried, the title compound was obtained as a solid (13 mg, 71% yield, HCl salt, it is regioisomers). MW/HCl=448.41. 1H NMR (DMSO-D6, 360 MHz) δ 8.0 (s, brs, 1H), 7.63 (d, J=7.6 Hz, 2H), 7.32 (d, J=7.6 Hz, 1H), 7.27 (d, J=3.6 Hz, 1H), 4.32 (s, 2H), 2.74 (q, J=6.8 Hz, 2H), 2.50 (s, 3H), 1.11 (t, J=6.8 Hz, 2H). MS: ESI+, m/z 412 [M+H]+. LCMS: 98.6%.
