実験手順

A rapidly stirred mixture of ethyl acetate and saturated aqueous sodium bicarbonate containing commercially available 6-(trifluoromethyl)quinolin-4-amine (558 mg, 2.63 mmol) was cooled to 0° C. and treated dropwise with benzyl chloroformate (1.10 mL, 3.29 mmol). After stirring overnight warming to room temperature, the aqueous layer was removed and the organic layer concentrated in vacuo. Purification of the residue by flash chromatography (silica gel, 0-20% MeOH/Ethyl acetate) yielded the product.
