Participants

Reaction Steps

To a stirring solution of 2-trifluoromethoxybenzoic acid (3.6 g, 17.5 mmol, Avocado) in dry CH2Cl2 (150 mL) with DMF (0.5 mL) was added a 2M solution of oxalyl chloride in CH2Cl2 (17.5 mL) dropwise over 30 nin. The reaction was stirred for 4 h and then conc. in vacuo to a white solid. The solid was dissolved in CH2Cl2 (150 mL) and reacted with diethylamine (3.2 g, 43.8 mmol, Aldrich) the reaction was stirred for 16 h and then conc. in vacuo to a yellow solid. The solid was purified by radial chromatography (SiO2, 1:5, EtOAc:hexanes) to yield 4.3 grams (94%) of the product as a colorless oil. MS (ESI) 262 (M+H).
