Reaction Steps
N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.39 g, 2.03 mmol) and 1-hydroxybenzotriazole (0.366 g, 2.71 mmol) were added to a stirred mixture of IM46 (0.22 g, 1.36 mmol) and commercially available (R)-2-amino-2-(6-trifluoromethyl-pyridin-3-yl)-ethanol hydrochloride (Supplier Netchem Inc., Catalog No 517882) (0.494 g, 2.03 mmol) and N,N-diisopropylethylamine (0.472 ml, 2.71 mmol) in THF (20 ml). The solution was stirred at rt overnight. Water was added and the mixture was extracted with EtOAc (3×80 ml). The combined organic phases were washed with brine, dried over MgSO4, filtered and the solvent was evaporated of in vac. The crude product was purified by silica gel chromatography (EtOAc in heptanes 10:1). Yield of Compound 22475 mg (78%). 1H-NMR (500 MHz, DMSO) δ 8.77 (d, 1H), 8.74 (s, 1H), 8.00 (d, 1H), 7.88 (d, 1H), 7.27 (m, 2H), 7.18 (m, 1H), 7.13 (d, 2H), 5.04 (m, 2H), 3.64 (m, 2H), 2.22 (m, 1H), 2.07 (m, 1H), 1.37 (m, 1H), 1.37 (m, 1H), 1.23 (m, 1H). LC-MS (m/z) 351.1 (MH+), tR=1.51 min (method A).
