Reaction Steps

Ethyl 2-bromo-2-phenylacetate (0.29 mL, 1.64 mmol), 3-ethylaniline (0.31 mL, 2.47 mmol), and N-ethyl-N-isopropylpropan-2-amine (0.43 mL, 2.47 mmol) are dissolved in acetonitrile (5 mL) and stirred under MW irradiation at 100° C. for 1 hour (Conversion complete by UPLC/MS-UV). Lithium hydroxide hydrate (207 mg, 4.94 mmol) and water (3 mL) are added and the mixture is stirred at RT for 16 hours. 4M HCl in dioxane is added until pH 1 and the solvents are evaporated. The residue is suspended in water, sonicated, cooled at 0° C. and filtered under suction. The recovered white solid is dried under vacuum at 40° C. overnight (414 mg, 86% yield).
