Reaction Steps

In an 4-mL was charged with 2-[4-[[2-(5-Chloro-2-thienyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl]amino]phenyl]acetonitrile (20 mg, 0.055 mmol), azidotrimethylsilane (80 mg, 1.44 mmol) and tetrabutylammonium fluoride trihydrate (25 mg, 0.07 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). The solid thus obtained was further triturated with dichloromethane (4 ml) to give the title compound (11 mg, 45% yield, HCl salt, it is regioisomers). MW/HCl=446.36. 1H NMR (DMSO-D6, 360 MHz) δ 7.76 (m, 3H), 7.30 (d, J=7.9 Hz, 2H), 7.23 (d, J=3.6 Hz, 1H), 4.29 (s, 2H), 2.92 (t, J=6.8 Hz, 2H), 2.86 (t, J=6.8 Hz, 2H), 2.11 (t, J=6.8 Hz, 2H). MS: ESI+, m/z 410 [M+H]+. LCMS: 97%.
