Reaction Steps

3-(5-(5-(3-(methylsulfonyl)phenyl)thiophen-2-yl)-3-(trifluoromethyl)-1H-pyrazol-1-yl)phenol (120 mg, 0.26 mmol), 2-(dimethylamino)ethanol (46 mg, 0.52 mmol) and triphenylphosphine (138 mg, 0.52 mmol) were dissolved in a mixture solvent of anhydrous THF (2.5 mL) and DCM (2.5 mL) and cooled off at 0° C. under nitrogen atmosphere. To this solution was added diisopropyl azodicarboxylate (111 mg, 0.52 mmol). The reaction mixture was stirred vigorously and warmed up to mom temperature overnight. The solvent was evaporated in vacuo and the residue was purified by HPLC, providing the product (61 mg, 44%). 1H-NMR (Acetone-d6): δ 8.13 (m, 1H), 7.93 (m, 1H), 7.90 (m, 1H), 7.71 (m, 1H), 7.60 (m, 1H), 7.47 (m, 1H), 7.17-7.09 (br, 5H), 4.12 (t, J=5.8 Hz, 2H), 3.18 (s, 3H), 2.65 (t, J=5.8 Hz, 2H), 2.21 (s, 6H). MS (ES): 536 [M+H]+.
