Reaction Steps

To a solution of 3-{1-[(3-chloropropyl)sulfonyl]-4-piperidinyl}-5-phenyl-1H-indazole-7-carboxamide (Intermediate 22) (20 mg, 0.0435 mmol) in acetonitrile (1 mL) was added K2CO3 (27 mg, 0.174 mmol), 2-(2-piperazinyl)ethanol (20 uL, 0.219 mmol) and sodium iodide (0.8 mg, 0.00435 mmol). The reaction mixture was heated to 60° C. for 14 hrs. The solution was filtered and concentrated. The residue was purified by using a Gilson semi-preparative HPLC system with a YMC ODS-A (C-18) column 50 mm by 20 mm ID, eluting with 10% B to 80% B in 10 min, hold for 1 min where A=H2O (0.1% trifluoroacetic acid) and B=CH3CN (0.1% trifluoroacetic acid) pumped at 25 mL/min to afford the title compound (7.0 mg, 30%).
