A solution of (S)-2-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenylcarbamoyl]-pyrrolidine-1-carboxylic acid benzyl ester (93.8 mg, 0.21 mmol), cyclopropanecarboxylic acid 4-bromo-benzylamide (50.6 mg, 0.20 mmol), and Pd[P(Ph)3]4 (13.7 mg, 5.7 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 15.0 mg. MS: 498.2 (M+H+); H1 NMR (DMSO-d6): δ (ppm) 0.61-0.79 (m, 4H), 1.56-1.69 (m, 3H), 2.11-2.35 (m, 1H), 3.38-3.59 (m, 2H), 4.25-4.43 (m, 3H), 4.89-5.15 (m, 2H), 7.00-7.65 (m, 12H), 7.85-7.95 (m, 1H), 8.51-8.63 (m, 1H), 10.07-10.16 (s, 1H).
