To a stirred solution of 5-(5-amino-3-tert-butyl-pyrazol-1-yl)-2-chloro-phenol (WO2007/091152, which is incorporated herein by reference; 200 mg, 0.75 mmol), 2-N morpholino ethanol (137 μL, 1.13 mmol) and Ph3P (394 mg, 1.50 mmol) in THF (7.5 mL) at 0° C. was added DEAD (236 μL, 1.50 mmol). After 1 h, the reaction mixture was diluted with water and extracted with DCM. The combined organics were dried and concentrated in vacuo. The residue was purified by FCC, using 0-5% [2M NH3 in MeOH] in DCM, to give the title compound (228 mg, 80%). LCMS (Method 3): Rt 2.28 min, m/z 379 [MH+].
