Reaction Steps

A solution of (S)-2-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenylcarbamoyl]-pyrrolidine-1-carboxylic acid benzyl ester (93.7 mg, 0.21 mmol), 3-bromo-N-cyclopropyl-benzamide (50.0 mg, 0.21 mmol), and Pd[P(Ph)3]4 (12.8 mg, 5.3 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 5.1 mg. MS: 484.2 (M+H+); H1 NMR (DMSO-d6): δ (ppm) 0.54-0.78 (m, 4H), 1.77-2.05 (m, 3H), 2.14-2.37 (m, 1H), 2.80-2.94 (m, 1H), 3.40-3.58 (m, 2H), 4.30-4.44 (m, 1H), 4.38-5.14 (m, 2H), 7.00-8.07 (m, 13H), 8.49-8.59 (m, 1H), 10.10-10.09 (s, 1H).
