Participants

Reaction Steps

To a solution of [2-(4-trifluoromethyl-phenyl)-ethyl]-(6-trifluoromethyl-pyridin-3-yl)-amine (50 mg) in CH2Cl2 (3 mL) was added under a nitrogen atmosphere at 0° C. benzoyl formic acid (1.1 eq., commercially available) and EDC (1.1 eq). After stirring for 12 h a ambient temperature, the mixture was washed with aqueous Na2CO3 (saturated, 2.5 mL) and water (2.5 mL), the combined aqueous layers were extracted with CH2Cl2 (3×2.5 mL) and the combined organic layers dried over sodium sulfate. Concentration and purification by chromatography (SiO2, heptane:ethyl acetate=95:5 to 60:40) afforded the title compound (46 mg, 66%) as a light yellow solid. MS m/e: 467.2 [M+H]+.
