To a solution of (R)-1-(2,6-dimethylphenyl)-3-isopropyl-5-oxopyrrolidine-3-carboxylic acid (25 mg, 0.091 mmol) and methanesulfonyl chloride (9 μL, 0.12 mmol) in THF (0.9 mL) at 0° C. was added diisopropylethylamine (0.047 mL, 0.27 mmol). The solution was stirred 15 min at 0° C., warmed to ambient temperature, and 3-isopropoxy-5-(trifluoromethyl)benzenamine (39 mg, 0.18 mmol) was subsequently added and the solution was heated at 55° C. overnight. The following day, the reaction mixture was purified via preparative HPLC to afford the desired amide as a white solid. 1H NMR (400 MHZ, CDCl): δ 9.91 (s, 1H), 7.59 (s, 1H), 7.56 (s, 1H), 7.04-7.16 (m, 3H), 6.90-6.94 (m, 1H), 4.65 (septet, J=6.0 Hz, 1H), 3.97 (d, J=10.4 Hz, 1H), 3.66 (d, J=10.8 Hz, 1H), 3.04 (d, J=17.2 Hz, 1H), 2.66 (d, J=17.2 Hz, 1H), 2.36 (septet, J=6.8 Hz, 1H), 2.16 (s, 3H), 2.00 (s, 3H), 1.29 (d, J=6.0 Hz, 6H), 0.96 (t, J=6.4 Hz, 6H). LC-MS Rt (retention time): 3.08 min; MS: (ES) m/z 477 (M+H+).
