実験手順

3-(4-Fluorophenyl)-2-(trifluoromethyl)-5,6,7,8-tetrahydroimidazo[1,2-a]pyrazine (I14) (285 mg, 1 mmol) and diethylaminomethyl polystyrene (1000 mg, 3.20 mmol) were slurried in dichloromethane (DCM) (10 mL) and treated with 2-chloro-3-(trifluoromethyl)benzoyl chloride (267 mg, 1.100 mmol). The slurry was stirred at RT for 24 h, whereupon the resin was filtered and washed with dichloromethane (20 mL). The filtrate was concentrated in vacuo to afford crude product. The product was purified by flash chromatography (Isolera, 10 g, 0-100% ethyl acetate/iso-hexane) to afford product in 428 mg.
