Reaction Steps

A mixture of {4-[4-(6-Bromo-1H-indazol-3-yl)-[1,2,3]triazol-1-yl]-phenyl}-morpholin-4-yl-methanone (150 mg; 0.33 mmol; 1.0 eq.), propargyl alcohol (39 μl; 0.66 mmol; 2.0 eq.) and Pd(PPh3)4 (19 mg, 0.02 mmol, 0.05 eq.) in pyrrolidine (1.5 mL) was heated O/N at 80° C. in a sealed tube. The reaction mixture was then diluted with DCM and washed with a saturated solution of NH4Cl (three times) and brine. Organic phase was dried over magnesium sulfate, filtered and concentrated. Purification by preparative HPLC gave the title compound as a beige solid (40 mg, 28%). 1H NMR (300 MHz, DMSO-d6-d6): 13.50 (brs, 1H), 9.42 (s, 1H), 8.34 (dd, J=8.5 Hz, 1.0 Hz, 1H), 8.15 (d, J=8.6 Hz, 2H), 7.70-7.67 (m, 3H), 7.28 (dd, J=8.5 Hz, 1.0 Hz, 1H), 5.40 (t, J=6.0 Hz, 1H), 4.35 (d, J=6.0 Hz, 2H), 3.64 (m, 6H), 3.47 (m, 2H).
