Procedure
To a solution of 2-(2-(4-chloro-1-methyl-1H-pyrazol-5-yl)-4-(3-(trifluoromethyl)benzamido)phenoxy)acetic acid (0.060 g, 0.13 mmol) and N,N-diisopropylethylamine (0.034 g, 0.26 mmol) in dichloromethane (1.3 mL) was added BTU (0.075 g, 0.20 mmol) followed by 2-methoxyethylamine (0.015 g, 0.2 mmol). After 1.5 hours the reaction was diluted with ethyl acetate, washed with water, 1 M HCl (×3) and brine, dried over magnesium sulfate and concentrated. The residue was purified by flash chromatography (1:1-1:0 EtOAc/hexane) to give a white solid (57.0 mg, 84%).
