Reaction Steps

A mixture of {5-tert-butyl-2-[3-(2-hydroxy-ethoxy)-phenyl]-2H-pyrazol-3-yl}-carbamic acid 2,2,2-trichloro-ethyl ester (WO 2007/063868, which is incorporated herein by reference in its entirety, 287.6 mg, 0.638 mmol), Intermediate 18a (140 mg, 0.425 mmol) and DIPEA (223 μL, 1.28 mmol) in dioxane (10 mL) was stirred at 60° C. for 18 h. The volatiles were concentrated in vacuo and the resultant residue was purified by FCC, using 0-10% [2M NH3 in MeOH] in DCM, to afford the title compound (222 mg, 82%). LCMS (Method 3): Rt 3.35 min, m/z 631 [MH+].
