Reaction Steps

To a solution of N-boc-L-proline (0.50 g, 2.3 mmol) and (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (1.02 g, 2.3 mmol) in DCM was added triethylamine (1.40 g, 13.8 mmol) and the reaction mixture was stirred for 30 minutes. C-(4-Chloro-pyridin-2-yl)-methylamine dihydrogenchloride (0.50 g, 2.30 mmol) was added and the reaction mixture was stirred for 12 hours. Water was added and the reaction mixture was extracted with DCM. The organic layers were combined, dried with Na2SO4, filtered, concentrated and purified by FCC (0-60% EtOAc in hexane) to provide the desired product (0.93 g, 93%). 1H NMR (400 MHz, DMSO) δ 8.62-8.51 (m, 1H), 8.47 (dd, J=9.8, 5.3, 1H), 7.56-7.31 (m, 2H), 4.45-4.27 (m, 2H), 4.20-4.09 (m, 1H), 3.51-3.24 (m, 2H), 2.26-2.05 (m, 1H), 1.95-1.69 (m, 3H), 1.48-1.24 (m, 9H).
