Procedure

To a microwave vial, 5-(6-amino-5-bromopyridin-3-yl)piperidin-2-one (45 mg, 0.167 mmol), (S)-(4-((1-(3-chlorophenyl)-2-hydroxyethyl)carbamoyl)-3-fluorophenyl)boronic acid (56.2 mg, 0.167 mmol), PdCl2(dppf) (12.19 mg, 0.017 mmol), DME (1111 μl, Ratio: 2.000), and Na2CO3 (2M solution) (555 μL, Ratio: 1.000) were added. The reaction mixture was heated at microwave reactor for 10 min at 120° C. LCMS—0.58 min, MH+483.2; 0.85 min, MH+613.3. After anhydrous sodium sulfate were added to remove water, the reaction mixture was filtered off and dried in vacuo. The small portion was purified by prep HPLC yielding 4-(2-amino-5-(6-oxopiperidin-3-yl)pyridin-3-yl)-N—((S)-1-(3-chlorophenyl)-2-hydroxyethyl)-2-fluorobenzamide as a diastereomeric mixture (12%). LCMS (m/z): 483.3 (MH+), 0.56 min; 1H NMR (400 MHz, CD3OD) δ ppm 7.89 (m, 1H), 7.80 (m, 2H), 7.42-7.30 (m, 3H), 7.30-7.24 (m, 2H), 7.25-7.15 (m, 1H), 5.18-5.03 (m, 1H), 3.87-3.64 (m, 2H), 3.47-3.35 (m, 2H), 3.11-2.97 (m, 1H), 2.46-2.30 (m, 2H), 2.08-1.91 (m, 2H).
