Reaction Steps

To a solution of (2-{[2-(4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}phenyl)ethyl]oxy}-4-oxo-1,4-dihydro-5-pyrimidinyl)acetic acid (91 mg, 0.194 mmol) in THF (2 mL) was added EDC (149 mg, 0.776 mmol) and HOBT (89 mg, 0.582 mmol). The mixture was stirred at room temperature for 15 min and acetohydrazide (21.57 mg, 0.291 mmol) was added. The mixture was stirred at room temperature overnight. Purification via reverse phase flash chromatography then afforded the title compound (28 mg, 0.053 mmol, 27.5% yield). LCMS: rt=3.04 min, [M+H+]=525
