실험 절차

To a solution of 5-(5-Amino-3-tert-butyl-pyrazol-1-yl)-2-chloro-phenol (WO2011/154734A1, which is incorporated herein by reference, 340 mg, 1.28 mmol), 2-(tetrahydro-pyran-2-yloxy)-ethanol (0.26 mL, 1.92 mmol) and Ph3P (671 mg, 2.56 mmol) in dry THF (10 mL) was added diethylazodicarboxylate (0.41 mL, 2.56 mmol) and the mixture stirred for 10 min. Water (4 drops) was added and the mixture concentrated in vacuo. The residue was purified by FCC, using 0-50% EtOAc in cyclohexane, to give the title compound (450 mg, 89%). LCMS (Method 3): Rt 3.73 min, m/z 394 [MH+].
