Combined 5-[2-(Pyridin-3-ylamino)-pyrimidin-4-yl]-thiophene-2-carboxylic acid (22 mg, 0.065 mmol), DIEA (27 uL, 0.195 mmol), and HATU (36.8 mg, 0.097 mmol) in DMA (0.5 mL) in a Smith microwave vial. Added 3-ethylamino propionitrile (10.9 uL, 0.097 mmol) and heated in microwave for 900 seconds at 90° C. The crude mixture was purified by prep LCMS to afford title compound (2.7 mg, 10.9%). MS: m/z 379 (M+H+). 1H NMR (500 MHz, DMSO-d6) δ1.203 (br t, 3H), 2.88 (br t, J=6.5 Hz, 2H), 3.65 (Br s, 2H), 3.70 (Br s, 2H), 7.33 (dd, J=5, 8.5 Hz, 1H), 7.469 (dd, J=1.5, 6.5 Hz, 1H), 7.497 (dd, J=1.5, 4 Hz, 1H), 7.985 (dd, J=1.5, 4 Hz, 1H), 8.16 (m, 1H), 8.22 (m, 1H), 8.56 (dd, J=1.5, 5 Hz, 1H), 8.95 (d, J=2.5 Hz, 1H), 9.91, (s, 1H).
