Triphenylphosphine → HCID 89558677, compound

Participants

Reaction Steps

A mixture of (4-iodo-1,3-dimethyl-1H-pyrazol-5-yl)methanol (75 mg), 4-hydroxybenzotrifluoride (48 mg), 40% diisopropyl azodicarboxylate (90 mg, toluene solution), triphenylphosphine (117 mg) and tetrahydrofuran (3.0 mL) was stirred at a room temperature overnight. Thereafter, water was added to the reaction solution, and the obtained mixture was then extracted with ethyl acetate. The organic layer was washed with water, and was then dried over anhydrous sodium sulfate, followed by vacuum concentration. The residue was purified by column chromatography (silica gel cartridge, hexane/ethyl acetate=90:10 to 50:50), so as to obtain the title compound (34 mg) in the form of a light yellow solid.
