Procedure

A solution of (S)-2-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenylcarbamoyl]-pyrrolidine-1-carboxylic acid benzyl ester (74 mg, 0.16 mmol), 2-(3-bromo-phenyl)-N-cyclopropyl-acetamide (42.0 mg, 0.17 mmol), and Pd[P(Ph)3]4 (14.3 mg, 7.5 mol %) in methanol (2 mL), NaHCO3 (sat. aq., 300 μL), and DMF (400 μL) was degassed and heated to 70° C. overnight in a sealed vial. The reaction was cooled, filtered, and purified by reverse phase HPLC to give the desired product. Yield 5.3 mg. MS: 498.2 (M+H+); H1 -NMR (DMSO-d6): δ (ppm) 0.31-0.39 (m, 2H), 0.52-0.60 (m, 2H), 1.74-2.00 (m, 3H), 2.10-2.30 (m, 1H), 2.50-2.62 (m, 1H), 3.34-3.54 (m, 2H), 4.28-4.38 (m, 1H), 4.85-5.08 (m, 2H), 6.95-7.55 (m, 12H), 7.80-7.92 (m, 1H), 8.05-8.18 (m, 1H), 10.05-10.12 (s, 1H).
