Reaction Steps

The compound was prepared according to Colotta et al. J. Med. Chem. 2006, 49, 6015. A solution of 4-trifluoromethoxyphenyl amine (500 milligrams (mg), 2.82 millimoles (mmol), 1.00 equivalent (eq)) and 2,5-diethoxy tetrahydrofuran (452 mg, 2.82 mmol, 1.00 eq) in glacial acetic acid (20 milliliters (mL)) was heated at 90° C. for 1 hour (h) before being dried onto silica gel. The residue was then slurried in refluxing hexane, filtered hot, and concentrated to dryness affording the desired intermediate (519 mg, 81%).
