Reaction Steps
To a solution of 3-aminomethyl-6-trifluoromethylpyridine (1 g, 4.7 mmol) in THF (30 mL) was added CDI (2.1 mol eq) and the mixture was heated at 70° C. overnight. The reaction mixture was evaporated, water was added and the aqueous phase was extracted with EtOAc (3×20 mL). The recombined organic phases were anhydrified over Na2SO4 and evaporated at reduced pressure. The oil obtained (0.8 g, 2.96 mmol) was dissolved in DMF (20 mL) and the bicyclic amine 1f was added (0.8 mol eq, 0.47 g), then the mixture obtained was heated at 100° C. overnight. The solvent was removed at reduced pressure and the residue was purified by chromatography (100% EtOAc) to obtain the product as a pale yellow solid (0.37 g, 42% Yield). 1HNMR (DMSO, 200 MHz) δ 4.39 (d, 2H, J=6), 4.61 (s, 2H), 6.46 (dd, 1H, J=2), 6.81 (t, 1H, J=8), 7.43 (t, 1H), 7.68 (dd, 1H, J=2), 7.90 (m, 2H), 8.18 (s, 1H), 8.69 (s, 1H), 10.66 (s, 1H). [M+1] 355.88 (C15H13F3N3O3 requires 355.27).
