Procedure

To a solution of 1-(3-(8-(aminomethyl)imidazo[1,2-a]pyridin-3-yl)-5-isopropoxyphenyl)-3-(2,2,2-trifluoroethyl)urea (26 mg, 0.062 mmol) in DCM (3 ml) was added DIEA (0.075 ml, 0.432 mmol) and HATU (35.2 mg, 0.093 mmol) and finally propiolic acid (4.95 μl, 0.080 mmol). Reaction was stirred for 30 minutes at room temperature. Reaction was loaded directly onto silica column and purified by flash chromatography (0-10% CH2Cl2/MeOH) to give the title compound (19 mg, 0.040 mmol, 65.0% yield) as an off white solid. MS (ES+) C23H22F3N5O3 requires: 473. found: 474 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ 9.34 (s, 1H), 8.92 (s, 1H), 8.47 (d, J=6.8 Hz, 1H), 7.74 (s, 1H), 7.17 (d, J=1.9 Hz, 2H), 7.10 (s, 1H), 6.98 (s, 1H), 6.82 (s, 1H), 6.74 (s, 1H), 4.69-4.58 (m, 2H), 3.93 (dd, J=9.7, 6.4 Hz, 2H), 2.72-2.64 (m, 1H), 1.30-1.19 (m, 6H).
