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), cyclopropanecarboxylic acid 3-bromo-benzylamide (41.7 mg, 0.16 mmol), and Pd[P(Ph)3]4 (15.1 mg, 8.0 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 5.0 mg. MS: 498.3 (M+H+); H1 NMR (DMSO-d6): δ (ppm) 0.55-0.70 (m, 4H), 1.50-1.60 (m, 1H), 1.73-1.98 (m, 3H), 2.07-2.29 (m, 1H), 3.35-3.56 (m, 2H), 4.24-4.37 (m, 3H), 4.85-5.08 (m, 2H), 6.97-7.54 (m, 12H), 7.63-780 (m, 1H), 8.50-8.59 (m, 1H), 10.06-10.13 (s, 1H).
