反応手順

A mixture of 3-(but-3-ynyl)-5-tert-butylthiazol-2(3H)-imine p-toluenesulfonate (prepared as described in US20080242654) (2.6 g, 6.83 mmol) and 2-fluoro-5-(trifluoromethyl)benzoyl chloride (1.55 g, 6.83 mmol) in anhydrous CH2Cl2 (30 mL) was treated dropwise at 0° C. with triethylamine (1.91 mL, 1.38 mmol). The mixture was allowed to warm to room temperature and stirred for 14 hours. The mixture was then washed with water, brine, dried with MgSO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography and eluted with hexane-EtOAc (2:1) to afford 2.5 g of the title compound. MS (DCI/NH3) m/z 399 (M+H)+.
