Procedure

N,N-dimethylformamide (1.88 mL) was added to a vial containing 4-(1-(3,5-dimethyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenoxy)butyl)benzoic acid (122.0 mg, 0.28 mmol), ethyl 3-aminopropanoate hydrochloride (86.6 mg, 0.56 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (214.0 mg, 0.56 mmol). Diisopropylethylamine (0.25 mL, 1.41 mmol) was then added. After stirring for 4 hours, the reaction was diluted with saturated ammonium chloride and extracted three times with diethyl ether. The combined organics were dried over sodium sulfate, filtered and concentrated. Purification by column chromatography (0-25% ethyl acetate in heptane) afforded (+/−)-ethyl 3-(4-(1-(3,5-dimethyl-4-(4-(trifluoromethyl)-1H-pyrazol-1-yl)phenoxy)butyl)benzamido)propanoate (117 mg, 78% yield). 1H NMR (400 MHz, CDCl3, δ): 7.87 (s, 1H), 7.73 (d, J=8.0 Hz, 2H), 7.65 (s, 1H), 7.39 (d, J=8.2 Hz, 2H), 6.84 (d, J=5.9 Hz, 1H), 6.57 (s, 2H), 5.15 (dd, J=7.8, 5.1 Hz, 1H), 4.17 (q, J=7.1 Hz, 2H), 3.71 (q, J=6.0 Hz, 2H), 2.63 (t, J=5.7 Hz, 2H), 2.04-1.91 (m, 1H), 1.88 (s, 6H), 1.86-1.71 (m, 1H), 1.58-1.33 (m, 2H), 1.26 (t, J=7.0 Hz, 3H), 0.96 (t, J=7.4 Hz, 3H). MS (M+1): 532.
